An inner peripheral water entry reducing portion and an outer peripheral water entry reducing portion are provided. The inner peripheral water entry reducing portion includes an inner peripheral wall portion surrounding an output shaft. The outer peripheral water entry reducing portion includes an outer peripheral wall portion surrounding the inner peripheral wall portion. At least one inner peripheral opening of the inner peripheral water entry reducing portion and at least one outer peripheral opening of the outer peripheral water entry reducing portion are prevented from overlapping with each other in a circumferential direction of the output shaft.

Blower device for air-conditioning of vehicle

A round bar output shaft is provided and fitted into an anti-slip member so as to rotate integrally with the anti-slip member. A recess is formed on the anti-slip member to make the stress generated on the anti-slip member by the output shaft fitted in non-uniform around a periphery of the anti-slip member. While the anti-slip member is being molded, a weld line is formed in a low-stress-generating portion.

Fan attachment structure

A fan includes a cylindrical anti-slip member that is rotatable integrally with a fan body. The anti-slip member is a molded product of a resin material with higher mechanical strength than the resin material of the fan body. A round bar output shaft is fitted into the anti-slip member. Recesses are formed on the outer peripheral surface of the anti-slip member.
