Abstract
A stator core of an AC generator for vehicles is laminated by helically winding a band-like steel plate and is formed to be approximately cylindrical. A yoke of the stator core is held between a pair of frames. An axial extending groove-like recess is provided in the outer peripheral portion of the stator core, and a through-bolt is arranged within the recess. It is possible to provide an AC generator for vehicles at low cost in which an axial center position of the through-bolt is controlled to thereby considerably reduce a moment component when the through-bolt is axially fastened to prevent an occurrence of looseness of the through-bolt and which prevents output from lowering, is small in size, is excellent in the resistance to vibration, and is low in noise.
