Patent ID: 7877857

Claim:
A manufacturing method of an electric motor, comprising electrically connecting a plurality of coils to a commutator, which includes a plurality of commutator segments that are arranged one after another in a circumferential direction of a generally cylindrical dielectric body along an outer peripheral surface of the dielectric body, wherein: each of the plurality of commutator segments includes: a slidably contacting portion that is provided in one axial side of the commutator segment and is slidably contactable with each of a plurality of power supply brushes; a claw portion that is provided in the other axial side of the commutator segment and to which a corresponding one of the plurality of coils is engageable; and a bending fulcrum portion that is formed on a claw portion side of the slidably contacting portion in an axial direction of the commutator, wherein the bending fulcrum portion is bendable upon radially inwardly pressing the claw portion to bend a claw portion side region of the commutator segment, which is located between the bending fulcrum portion and the claw portion in the axial direction of the commutator, against the dielectric body using the bending fulcrum portion as a fulcrum; and a radially inner surface of the bending fulcrum portion and a radially inner surface of the claw portion side region directly contact the dielectric body; and the electrically connecting of the plurality of coils to the commutator includes radially inwardly pressing and welding the claw portion of each of the plurality of commutator segments, to which the corresponding one of the plurality of coils is engaged, through use of a fusing electrode in such a manner that the bending fulcrum portion of the commutator segment is bent by an urging force of the fusing electrode, which is applied to the claw portion.
