Abstract

PURPOSE:To obtain a brush holder case which can prevent cracks and damage and which has light weight and high reliability by employing polyester series resin for the case and burying plates of different materials at least at the holder of the brush. CONSTITUTION:A brush holder case body 21 is formed of polyester resin having excellent impact resistance, heat resistance and electric characteristics. Plates 10 to be buried and of different material from the polyester resin are integrally buried at the position to be buried with buried metal 24 at least to enhance the bending strength. In this manner, a brush holder case which has excellent dynamic and static characteristics can be obtained.
