ABSTRACT:
An automobile wiper device has a pair of wiper arms movable between full-concealed position and semi-concealed position. The wiper arm reciprocates between the lower and upper turning positions, by the rotating force transmitted from the driving motor through the driving mechanism. The driving mechanism includes a driving lever secured together with the wiper arm to the rotary shaft fixed on the vehicle body, a switching lever coupled to the crank arm of the driving motor through a link shaft, and a turn-over spring secured between the switching lever and the driving lever. When the wiper resting position is jammed with snow, said switching lever acts to shift the lower turning position of the wiper arm from the full-concealed position to the semi-concealed position upon the rotating force being transmitted from the driving motor exceeds the bias force of the turn-over spring.
