ABSTRACT:
A positive-side brush and a negative-side brush are held by a motor frame and contact the sliding-contact surface of a commutator. A displacement member switches the state of one brush connected with a starting power source from an ON state in which the brush contacts the commutator to an OFF state in which the brush is separated from the commutator or vice versa. The displacement member comprises a slide rail holding the brush movably, a return spring which returns the brush to the OFF state, and a push button which is manually operated to press the brush against the commutator so as to turn on the brush. A starting electric circuit can be opened or closed by operating the push button.
