PROBLEM TO BE SOLVED: To provide an AC generator for vehicle which prevents generation of a warp on a negative-pole side radiator fin. SOLUTION: A rectifier 6 for the AC generator for vehicle has a positive-pole side radiator fin and the negative-pole side radiator fin 68 facing each other apart in the axial direction interposing a terminal board 61. The negative-pole side radiator fin 68 has an approximately arc shape having an arc-angle 180 degrees or more as a whole and consisting of two partial radiator fins 68A and 68B separated each other in the proximity of the center. Two fixing parts 69 are formed near each external shape of the partial radiator fins 68A and 68B. Assembling to the frame of the rectifier 6 is made by tightening each screw which is in a state inserted in each fixing part 69 into each threaded hole formed on the frame. |
