A brush holding device includes a dielectric resin circuit board and at least one metal brush holder secured to the circuit board at its base portion. Each brush holder includes a receiving recess that receives a brush and a spring for urging the brush against a commutator. A side wall of the brush holder located at a radially outer side of the brush holder includes an engaging piece that resiliently engages against an inner peripheral surface of an outer peripheral wall of the circuit board.

Wiper device includes an arm system composed of an arm head, arm retainer and an arm piece that are connected together. The arm system has a movable portion which is capable of moving a wiping direction. A rubber vibration damper is disposed at the movable portion which is formed, for example, between the arm retainer and the arm piece of the arm system. When the wiper device is operating, an exciting force produced between the surface of a windshield and a wiper blade is transmitted to the arm piece and tends to oscillate the arm piece in the wiping direction about the movable portion. In this instance, the rubber vibration damper elastically deforms and dampens the vibrational force applied to the movable portion.
