ABSTRACT:
In the present invention, by selecting an optimum combination of plating layer materials or materials, not only the manufacturing cost of motor brush is reduced but also a plating layer having excellent characteristics is formed in a narrow width on the surface of brush base material so as to have a predetermined thickness. The present invention is formed by a brush sliding portion that slides on a motor commutator and a plate-shaped brush base material that is slender as a whole and supports the brush sliding portion. This brush sliding portion is formed by Pd plating portion formed over a predetermined length on a part in the lengthwise direction of the brush base material that supports the brush sliding portion. This Pd plating is applied on the brush base material via backing Ni plating.
