Title:
AIR CONDITIONING DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/009196
Kind Code:
A1
Abstract:
This air conditioning device is provided with: an air conditioning case (10); a fan (20); a motor (30) that rotates the fan; and a motor holder (40) having a cylindrical portion (41) in which the motor is housed. A groove formation portion (84) where a groove (80) which is recessed toward one side in the center axis (40a) direction of the cylindrical portion and which extends in the circumferential direction of the cylindrical portion is formed, is provided in the outer circumferential surface of the cylindrical portion. A projection (90) which projects toward the one side in the center axis direction of the cylindrical portion and which extends in the circumferential direction of the cylindrical portion, is provided on the air conditioning case. Contact suppression portions (82, 83, 91, 92) for suppressing the contact area between the groove and the projection are provided to the groove and/or the projection. The contact suppression portions reduce the contact area between the groove and the projection to be smaller than the cross-sectional area, orthogonal to the center axis, of a portion of the projection positioned closer to the other side along the center axis of the cylindrical portion than the groove. Further, the contact suppression portions are deformed so that the groove and the projection are fitted.
