Abstract
In a rotor of an AC generator for a vehicle, a coil bobbin, around which rotor coil is wound, includes a bobbin body having a first through hole at a winding drum portion and is made of hard resin. A first hole member is kept at the first through hole and is made of good thermal conductivity rubber. An outer peripheral layer is formed integrally with the first hole member and is made of good thermal conductivity rubber covering the outer peripheral surface of the winding drum portion. An improved rotor of an AC generator for a vehicle is provided, in which a regular winding property of the rotor coil is improved and at the same time, heat of the rotor coil can be more effectively radiated to the rotor core side so that generator output can be improved.
