Abstract: 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.

Abstract: 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.
