ABSTRACT:
A rotating electric machine for a vehicle includes magnet holders for holding permanent magnets. The magnet holder is fitted between adjacent two claw-like magnetic poles of pole cores, and plural permanent magnets are provided to be magnetized for reducing magnetic-flux leakage between the magnetic poles. The magnet holder includes a radial outer surface, and a protrusion that protrudes from the radial outer surface to a radial outside around a center in a circumferential direction. Therefore, a thickness of the radial outside surface of the magnet holder increases, and its rigidity can be increased. Accordingly, it can prevent the radial outside surface of the magnet holder from being deformed due to centrifugal force, and it can prevent the magnet holder from being damaged.
