Claims

[Scope of utility model registration request]

The rotating shaft has a groove surrounding the outer periphery of the rotating shaft with the axis as the center, and a stepped surface located apart from the groove in the axial direction of the rotating shaft and extending in the radial direction, A fitted fan is pressed and fixed to the stepped surface by an elastic body fitted in the groove, wherein the stepped surface and a surface of the fan that is joined to the stepped surface have unevenness. A fixed structure of the fan characterized by being pressed by the fan.
