PURPOSE: A wiper device with a variable driving angle is provided to conveniently regulate the driving angle of wipers by changing the relative rotational angle between a guide unit and a connecting unit. CONSTITUTION: A wiper device with a variable driving angle comprises a wiper unit(10), a guide unit(40), and a fixing unit(50). The guide unit has a holding protrusion which is fitted in one of holding grooves formed at regular angle intervals in the fixing unit. The guide unit has an operating protrusion which is operated by a user through an opening(22) of a cover(20). Accordingly, the guide unit is rotated by an accurate desired angle and the user can recognize the driving angle of the wiper unit accurately. |
