Claims

[Scope of utility model registration request]

On the surface of an annular commutator provided concentrically at one shaft end of the rotor, which is rotatably received by both end brackets in the stator of the rotating electric machine,
A brush holding structure in which a columnar brush is held near and parallel to an inner wall of the one end bracket located on the uniaxial end side so that the tip surface of the brush is in sliding contact with the brush; a cylindrical part that is accommodated so as to be guided toward the child; a central part formed by a longitudinal metal piece and fixed to the outer circumferential surface of the cylindrical part; and a central part that extends from both ends of the central part to the outside and inside of the one end bracket. A holding member is provided with a leg piece having an outwardly extending portion and an inwardly extending portion respectively extending to the left side, and the tip of the outwardly extending portion and the tip of the inwardly extending portion of the leg piece are respectively provided. The one end bracket is solidified and molded with a liquid synthetic resin material in order to embed the leg piece in the one end bracket so as to extend outward and inward of the one end bracket and to integrate the leg piece into the one end bracket. A brush holding structure for a rotating electrical machine equipped with a commutator.
