ABSTRACT OF THE DISCLOSURE A wiper driving unit for driving a wiper for a vehicle such as a motor vehicle includes: a driving gear driven by a motor, for driving the wiper; and a clutch member formed of a conductive resilient plate, rotatably supported and rotatable together with the driving gear in the biasing direction only when the driving gear is rotated in the biasing direction. An engageable member on the driving side is projectingly provided on the driving gear, and an engageable member on the driven side is connected in operational association to the clutch member. The engageable member on the driving side and the engageable member on the driven side are engaged with each other to rotate the driving gear together with the clutch member in the same direction only when the driving member is rotated in the biasing direction. However, when an external force to rotate the driving gear in the reverse direction is applied, the both engageable members are disengaged from each other, and the clutch member does not follow the rotation of the driving gear in the reverse direction, whereby chattering is prevented which is caused by a relative backwardly moving phenomenon between the conductor plates connected to an electric circuit of the motor and a plurality of contacts provided on the clutch member.
