Abstract:
PROBLEM TO BE SOLVED: To prevent a commutator piece from floating from a resin molding section due to an external force received from a winding connected to a winding connection section.SOLUTION: A commutator 1 for rotary electric machine includes a plurality of annularly arranged commutator pieces 9, and a resin molding section 11 in which the plurality of commutator piece 9 are embedded. The plurality of commutator pieces 9 have a brush sliding section 13 with which a brush 5 is brought into slide contact, a hook section 17 to which an armature winding 15 is connected and that forms an annular portion having a larger diameter than that of an annular portion formed by the brush sliding section 13, and a contact section 19 which connects the brush sliding section 13 and the hook section 17 and is embedded in the resin molding section 11. In the portion embedded in the resin molding section 11 of the contact section 19, a width P on the side of a rear face 19b1 on the embedded side is wider than a width Q on the side of a surface 19b2.SELECTED DRAWING: Figure 3
