Abstract
Coils are electrically connected to a commutator, which includes commutator segments that are arranged one after another in a circumferential direction of a dielectric body along an outer peripheral surface of the dielectric body. Each commutator segment includes a slidably contacting portion, a claw portion and a bending fulcrum portion. The slidably contacting portion is provided in one axial side of the commutator segment and is slidably contactable with each brush. The claw portion is provided in the other axial side of the commutator segment and is engageable with the corresponding coil. The bending fulcrum portion is formed on a claw portion side of the slidably contacting portion and is bent upon radially inwardly pressing the claw portion by a fusing electrode.
