Claims

[Scope of Claim for Utility Model Registration] A wiper device comprising an arm head rotatably attached to the vehicle body, and a wiper arm whose proximal end is pivotally supported by the arm head and whose distal end has a wiper blade attached: A forward-side washer nozzle and a backward-side washer nozzle inject washing liquid to the forward-moving side and backward-moving side of the wiper blade, respectively, and the washer liquid is alternately supplied to the forward-moving side washer nozzle and the backward-moving side washer nozzle. The valve-side magnetic body includes a valve, a valve-side magnetic body that is provided on the valve side and operates together with the valve, and a fixed-side magnetic body that is provided at a predetermined position corresponding to the operating range of the valve-side magnetic body. and a valve switching mechanism that switches the valve to a state in which the washer liquid is supplied to the washer nozzle on the rotation direction side of the wiper blade at both ends of the arm head by interaction of the magnetic forces of the fixed side magnetic body. wiper device.
