PURPOSE:To simplify the installation of a terminal plate and to prevent poor contact as well by providing projections having elasticity at the joint surface of a holder body for the terminal plate. CONSTITUTION:Projections with elasticity or irregularity having almost same thickness as the plate thickness are provided at the junction surface of a holder body for a terminal plate 1. The irregularity d shall be limited to the range of maintaining the material elasticity. A hole a is also provided at the central part of the terminal plate and a lead wire 6 is fixed to the plate by soldering or brazing or the like. In this way, a terminal plate stopper will be omitted for easy assembly. Furthermore, contact with the plate and a brush holder will be maintained in good condition and poor contact will be prevented. |
