Patent ID: 7629719

Claim:
An AC generator for vehicles, comprising: a stator having a stator winding; a rotor disposed inside the stator so as to oppose to the stator; a field winding that generates magnetic flux to be supplied to the rotor; a rectifier including at least one radiating fin to which a plurality of rectifying elements are attached and a terminal mount in which a metal terminal is contained, the rectifying elements rectifying output voltage of the stator winding and outputting the rectified voltage, and the metal terminal connecting the rectifying elements to a lead of the stator winding; a housing that accommodates the stator and the rotor; and a rear cover that protects electrical components including the rectifier mounted on a rear-side end of the housing, wherein the terminal mount includes an L-shaped support having a radial extension, in which the metal terminal is contained and which radially extends about a rotary shaft of the rotor, and an axial extension, which extends from an end of the radial extension toward the rear cover along the rotary shaft, and at least one first guide molded integral with the L-shaped support, the radiating fin includes a second guide having a shape corresponding to a shape of the first guide, and one of the first guide and the second guide is inserted into the other of the first guide and the second guide.
