A wiper driving apparatus comprising: a drive gear 12 rotated by a motor 31; a clutch member 15 rotating together with the drive gear 12 only in a direction the drive gear 12 is biased to; a pair of electric conductor plates 24 and 25 for turning on and off an electric circuit of the motor 31; a pair of movable contacts 16 and 18 rotatable relatively with the electric conductor plates 24 and 25 in sliding contact with the electric conductor plates 24 and 25, respectively; and a housing 1 rotatably supporting the clutch member 15 with a supporting axle 14 and having the electric conductor plates 24 and 25 provided concentrically therewith; wherein both of the movable contacts 16, 18 and the clutch member 15 are rotated integrally with one another. The clutch member 15 is formed as a conductive member, one 16 of the movable contacts is formed integrally on the clutch member 15, and the electric conductor plate 24, on which the movable contact 16 slides, is disposed adjacently to the supporting axle 14.
