Abstract:
A motor holder (40) for a fan (20) includes: a tubular portion (41) in the shape of a tube which is disposed in a hole portion (10a) formed in an air conditioning case and which forms a motor accommodating space (410); a tubular duct portion (42) which communicates with the accommodating space and which extends from the tubular portion in a direction intersecting a rotation center line (20a) of the fan; and a tubular air introduction opening (43) which extends from the duct portion toward a ventilation passage for introducing a portion of air flowing through the ventilation passage into the duct portion. The air conditioning case includes a tubular air passage forming portion (190) which extends from the ventilation passage toward the air introduction opening, and which forms an air passage (18) for guiding said portion of the air flowing through the ventilation passage to the air introduction opening, wherein an inner circumferential surface of the air passage forming portion and an outer circumferential surface of the air introduction opening are in contact with one another and the air introduction opening is fixedly supported in the air passage forming portion, and the outer circumferential surface of the air introduction opening and the inner circumferential surface of the air passage forming portion are inclined in such a way as to move away from a centerline of the air passage with increasing distance in a direction moving away from the ventilation passage.
