Brush holding device, motor having the same, and method for assembling motor

摘要

Brush holding device (30) includes a brush (31), a brush holder (32), a torsion spring (33) and a support pin (34). The torsion spring (33) applies side pressure to the brush (31) by spring force exerted around the support pin (34) and also temporarily hold the brush (31) in the brush holder (32). When the temporarily held state of the brush holder (31) is relieved, the spring force of the torsion spring (33) urges the brush (31) toward a commutator (27).
