ABSTRACT:
A brush holding structure for guiding a brush to a commutator is supported in a motor case. The structure includes an insulator plate attached to the motor case. The insulator plate is provided with guide means for guiding the brush in a direction which is inclined to a radial direction of the commutator within a plane including the axis of the commutator. The structure further includes a plate-like spring which has, at both ends, coil portions for winding up. An intermediate part of the plate-like spring presses the brush against the commutator to hold the brush in contact with the commutator without any play.
