ABSTRACT:
A generator includes a case for accommodating a stator, a rotor and a fan. The case includes two end walls in an axial direction and a peripheral side wall. The case has plural axial opening portions which are provided in at least one of the two end walls and open approximately in the axial direction, and plural radial opening portions provided in the peripheral side wall. The fan is disposed at least at one axial end of the rotor to draw outside air through the axial opening portions and to discharge the drawn outside air through the radial opening portions. A cover member of the generator covers the axial opening portions from an outside of the case with clearances between the axial opening portions and the case. Accordingly, noise generated inside the case can be reflected by the cover member, and it can effectively reduce noise transmitted to an outside.
