ABSTRACT:
An alternator has a rotor having magnetic poles along a circumferential direction and a cooling fan fixed to an end surface of the rotor in an axial direction. The fan has wing portions disposed along the circumferential direction. One wing portion has a fan base extending on or over first and second magnetic poles, first and second fixing members, respectively, fixing first and second fixing portions of the base to the first and second poles, and a fan blade extending from the fan base toward the axial direction. The base or blade has a boundary portion at which a boundary line between the blade and base crosses over a side line of the second pole, and a first distance between the first fixing portion and the boundary portion is substantially equal to a second distance between the second fixing portion and the boundary portion.
