Abstract

PURPOSE: To slide the brush stably on suppressing the amplitude of vibration applied to the brush by providing a reinforce rib to the bend of the brush holder spring and by making the spring constants in the rotary and axial directions of the commutator greater.
CONSTITUTION: The reinforce rib 7 in which a bent rib 8 and a projected rib 9 are duplicated is provided to the bend 1 of the holder spring 2 that holds the brush and presses it on the commutator. In this way, since the spring constants in the rotary and axial directions Y, Z are made greater, the amplitude of very small vibration applied to the brush, which is caused by the rotation of commutator, can be made less and the brush can stably be slided even during a high speed rotation.
