Wiper driving apparatus

摘要

A wiper driving apparatus comprising: a drive gear rotated by a motor; a clutch member rotating together with the drive gear only in a direction the drive gear is biased to; a pair of electric conductor plates for turning on and off an electric circuit of the motor; a pair of movable contacts rotatable relatively with the electric conductor plates in sliding contact with the electric conductor plates, respectively; and a housing rotatably supporting the clutch member with a supporting axle and having the electric conductor plates provided concentrically therewith; wherein both of the movable contacts and the clutch member are rotated integrally with one another. The clutch member is formed as a conductive member, one of the movable contacts is formed integrally on the clutch member, and the electric conductor plate, on which the movable contact slides, is disposed adjacently to the supporting axle.
