PURPOSE: A conducting device between a stator and a rotor is provided to increase the lifetime of a brush by reducing abrasion between a commutator piece and the brush. CONSTITUTION: A commutator piece (2) is buried in the outer surface of a commutator base. A conductive ball (3) is rolled in contact with the commutator piece. A brush bracket (4) comes into contact with the conductive ball. A terminal (17) is connected to the brush bracket and passes through a stator (10). |
