This commutator (8) for an electric motor is equipped with: a roughly cylindrical commutator main body part (81) formed of resin; multiple plate-shaped commutator pieces (82) formed of an electroconductive material and arranged so as to be affixed to the outer peripheral surface of the commutator main body part (81) with approximately identical pitch in the circumferential direction; and risers (83), which are respectively formed integrally on one end of each of the multiple commutator pieces (82), and extend so as to bend up toward the other end of and face the commutator pieces (82), and on which coil wires (W) of the electric motor are wound. In addition, engaging means (83a) are provided at the tips of the risers (83) of the commutator (8) to prevent the wound coil wires (W) from detaching when fusing occurs. |
