BRUSH STRUCTURE OF MOTOR WITH BRUSH

摘要

PROBLEM TO BE SOLVED: To provide a brush structure of motor with brush in which the contact condition of the brush and a commutator is stabilized for a long period of time. SOLUTION: In the brush structure of motor with brush wherein the end part side of the flat type brush 30 is provided with a sliding part 31 for the commutator, the sliding part 31 is provided with a projection 32 in which the upper end part 320 is projected from the flat plate in the height assuring contact for the commutator. This projection 32 is formed with the press work and the upper end part 320 has the curved surface and is almost constant in the thickness toward the upper end part 320 from the root area.
