Abstract
A wiper motor has an output shaft, which is reciprocally pivoted forward and backward upon energization of the wiper motor and outputs a drive force for driving first and second wiper arms. A crank arm is integrally pivotably fixed to the output shaft. First and second connecting rods are pivotably connected to first and second connecting points, respectively, of the crank arm. A first lever arrangement is connected between the first connecting rod and the first wiper arm to reciprocally pivot the first wiper arm upon reciprocal movement of the first connecting rod. A second lever arrangement is connected between the second connecting rod and the second wiper arm to reciprocally pivot the second wiper arm upon reciprocal movement of the second connecting rod.
