As shown in FIG, 9, the fan motor holding member 40 is formed so that the guide wall 45 is almost in parallel with the standing wall 44. Though it is sometimes difficult that the guide wall 45 is formed inclined at a prescribed angle relative to the standing wall 44 , since it is enough that the fan motor holding member 40 is formed so that the guide wall 45 include a part to be parallel with the standing wait 44, it is possible to manufacture the fan motor holding member 40 easily.

The standing wall 44 connects with the support columns 31 and the motor mounting surfaces42 including the folding portion 46, The standing wall 44 projects toward the front side, is substantially perpendicular to the front surfaces of the support columns 3 1

In this embodiment, the guide wall 45 is the member which contact w i th the cylindrical main body portion 22 of the fan motor 20, and is formed so ns to be almost in parallel with the standing wall 44, The guide wall 45 includes one projection 45a which projects toward the area enclosed by the fan motor holding members 40, but is not limited to this. The guide wall may be informed to include plural projections which project toward the area enclosed by the fan motor holding members 40,

Advantages of the projection 45a include tout it is possible to prevent complication of an installation process of the fan motor 20 since it is easy to determine if the projection 45a is formed in the guide wall 45.

As such, since a distance between the standing wall 44 and a tip of the projection 45a is longer than that between the standing wall 44 and the guide wall 45 other than the tip of the projection 45a, the projection 45a i s contacted with the fan motor 20 surely. As a result, the fan motor 20 is held by tile guide walls 45 which is pressed toward the fan motor 20 by their elastic force A which is generated due to the deformation of the guide walls 45 (See FIG, 10.).

In this embodiment, though the fan motor holding member 40 is formed so that the guide wall 45 is almost in parallel with the standing wall 44, the fan motor holding member 40’ may be formed so that the guide wall 45 * has a portion where a distance between the standing wall 44 and the guide wall 45’ other than a part connecting with the folding portion 46 is longer than that be tween the standing wall 44 and the part connecting with the folding portion 46 (FIG, 11 ), The fan motor 20 is held by the guide walls 45* which are pressed toward the fan motor 20 by their elastic force which is generated due to the deformation of the guide walls 45 * . in this case, it is not always necessary to form the projection 45a in the guide wall 45’ if the guide wall 45’ is formed inclined at a prescribed angle relative to the standin wail 44.

Moreover, as shown in FIG.12. the guide wall 45* which is formed inclined at a prescribed angle relative to the standing wail 44 may include the projection 45a, since the fan motor 20 is held by the guide walls 45 which are pressed toward the fan motor 20 by their elastic force Which is generated due to the deformation of the guide walls 45 * . In this case, since it is easy to determine if the projection 45a is formed in the guide wall 45 * , it is possible to prevent complication of an installation process of the fan motor 20.

Furthermore, as sho wn in FIG.13, if the guide wall 45** is formed inclined at a prescribed angle relative to the standing wall 44, the end of the guide wail 45” on the side of the fan motor support 30 may be formed to be bent to the ride of the standing wall 44 since the fan motor 20 is held by the guide walls 45* * which are pressed toward the fan motor 20 by their clastic force which is generated due to the deformation of the guide walls 45*’. In this ease, it is possible to prevent the end of the guide wall from damaging the fan motor and improve the workability.

As shown in FIG 14, the projection 45a of the guide wall 45 is formed to be long sideways, for the purpose of improving in acceptability for the contact position between the fan motor 20 and the projection 45a of the guide wall 45, As such, the outdoor unit 100 is capable to temporary fix the fan motor 20 at the predetermined position of the fan motor support 30 mare surely and more easily by the simple constitution.

In this embodiment, the projection 45a of the guide wall 45 is formed to be long sideways, but not limited to this. The projection of the guide wall 45 is required to be formed to be long sideways when viewed from the vertical direction of the area enclosed by the fan motor holding members 40. For example, the projection of the guide wall 45 may be a long sideways rectangle, long; sideways rectangles, a long sideways ellipse, long sideways ellipses, a long sideways inclined rectangle, long sideways inclined rectangles, a long sideways inclined ellipse, long sideways inclined ellipses or the combination thereof.

Next, the operation of the outdoor unit 100 will be provided with reference to FIG.10. As mentioned above, the guide wall 45 is the member which contact with the cylindrical main body portion 22 of the fan motor 20, and is formed so as to be almost in parallel with the standing wall 44, The guide wall 45 includes one projection 45a which projects toward the area enclosed by the fan motor holding members 40.

Firstly, when the fan motor 20 is mounted to the fan motor support 30, the fan motor 20 is Inserted into the area enclosed by the fan motor holding members 40 from the side of fan motor holding member 40 toward the fan motor support 30.

Since the guide wall 45 has the portion 45a where a distance between the standing wall 44 and the guide wall 45 other than a part connecting with the folding portion 46 is longer than that between the standing wall 44 and the part connecting with the folding portion 46, the fan motor 20 is contacted with the guide wall 45 of the fan motor holding member 40.

Next, when the fan motor 20 is continuously inserted into the area enclosed by the fan motor holding members 40, the guide wall 45 deforms so that the guide wall 45 comes closer to the standing wall 44 because the standing wall 44 connects with the fan motor support 30, Namely, the fan motor bolding member 29 is configured to be bent and bowed when the fan motor 20 is held by the plural fan motor holding members 40 As such, the elastic force A is generated to the direction from the standing wall 44 toward the guide wall 45.

Therefore, in the area enclosed by the fan motor holding members 40, the fan motor 20 is held by the fan motor holding members 40 which press the guide walls 45 toward the fan motor 20 by their elastic force A, As a result, the outdoor unit 100 is capable to temporary fix the fan motor 20 at the predetermined position of the fan motor support 30 surely and easily by the simple constitution.

Moreover, since the fan motor 20 is capable to be fixed at the predetermined position of the fan motor support 30 by the screws 14 and so on, it is possible for the engineer to improve workabili ty including the installation of the fan motor 20 on the fan motor support 30.

Furthermore, even if the type of the fan motor 20* differs (tor example, the fan motor having slightly different diameter, the fan motor formed in a slightly different shape, the outdoor unit 100 for an air-conditioning apparatus is capable to temporary fix the fan motor 20* at the predetermined position of the fan motor support 30 surely and easily since tile fan motor holding member 40 is deformable.

Although specific embodiments of the invention have been disclosed and described as well as illustrated in the companying drawinp, it is simply for the purpose of better understanding of the principle of the present invention and it is not as a limitation of the scope and spirit of the teaching of the present invention. Adaption and modification to various structures such as design or material of the invention are possible and apparent to a skilled person without departing from the scope of the present invention which is to be determined by the claims.
