Abstract
A motor includes a brush configured to contact a commutator and a movement restricting structure configured to restrict a movement of the brush. The movement restricting structure has: a carbon holder for housing the brush while permitting a movement of the brush in the commutator radial direction; and a circumferentially restricting part for restricting a movement of the brush in the commutator circumferential direction. The circumferentially restricting part has a passing port formed by punching, through which the brush passes.
