ABSTRACT:
An automotive alternator includes a rear frame having a rear end wall and a cover member covering a brush device. The cover member is connected to the rear end wall of the rear frame, and a vibration-absorbing member made of a rubber material is disposed between the rear end wall and the cover member. The vibration-absorbing member has a cylindrical portion disposed between a center opening of the rear end wall and an extending portion of the cover member and a rear disc portion disposed between the rear end wall and a front surface of the cover member. The cylindrical portion is compressed in the radial direction while the rear disc portion is compressed in the axial direction, thereby alleviating vibration of the brush device in both the radial and the axial directions.
