PURPOSE:To easily adjust the error angle of a wiper blade through its small simple structure of a wiper by providing a pivot shaft to reciprocatively rotate a wiper arm, an eccentric bearing member to rotatably support the pivot shaft, and a rotating means for operatively associating the eccentric bearing member with the reciprocative rotation of the pivot shaft. CONSTITUTION:During the operation of a right wiper 10A, the driving power of a wiper motor is transmitted to a pivot lever 30 through a link rod 32 to reciprocatively rotate the pivot lever 30 and a pivot shaft 18 and further a wiper arm and a wiper blade. On the other hand, the driving power of the wiper motor is also transmitted to a lever 40 through a connecting rod 42 to rotate a gear 38. Since the gear 38 meshes with the gear part 28 of an inner gearing 24, which is rotated in a direction opposite to the rotational direction of the gear 38. The relative inclination of the pivot shaft 18 to a base plate 20 is therefore altered according to the rotation of the wiper arm for setting the error angle of the wiper blade within a fixed range even in the case of the large curvature of a window glass 16. |
