Abstract: This brush holder assembly for an electric machine includes a bearing-forming metal end cap (26) intended to be mounted on a carcass of the machine, and a set of members (28, 30, 32, 34) for electrical connection of the brushes mounted on the end cap (26) by means of rivets (50, 52) which each include a shank extending from one of the pieces consisting of the end cap and one of the members, passing through an orifice formed in the other piece and folded over against the latter. The shank is made of the same material as the piece from which it extends and includes a closed head.

Abstract: The electric machine includes a collector (60), a brush-holder assembly comprising an end cap (26) and a set of members (28, 30, 32, 34) for electrical connection equipped with guide cages (36, 38, 40, 42) suitable for accommodating a respective brush (44), in which a member (64) for limiting the radial displacement of the brushes in the absence of a collector is provided, the dimensions of the limiting member (64) being suitable for obtaining a tight fit of this member on the end cap (26). Application for the mounting of a brush holder for a motor-vehicle starter.
