Claims (1)

[Claims for Utility Model Registration] A pivot shaft is rotatably held in a pivot block fixed to the outer panel of the vehicle body, a pair of nozzles are attached to a wiper arm whose base is attached to the pivot shaft, and washer fluid is applied to the nozzle. In a vehicle washer device that sprays water from one side of the wiper arm just before the direction of movement of the wiper arm and sprays the windshield panel, the rotary disk disposed between the pivot block and the base of the wiper arm is arranged concentrically with the pivot shaft. Further, a ring-shaped valve body provided so as not to be relatively rotatable and loosely inserted around the outer periphery of the pivot shaft is tightly interposed between the rotary disk and the pivot block, and the pair of valve bodies are in communication with the nozzles and are adjacent to each other. a switching passage is formed in the rotating disc, and a valve hole is provided in the ring-shaped valve body to alternately communicate with the pair of switching passages by relative rotation of the ring-shaped valve body and the rotating disc. , the pivot block is provided with a guide passage that is constantly in communication with the valve hole and with the washer fluid supply source within the rotation range of the ring-shaped valve body, and the wiper arm is configured to rotate in the rotation direction from just before the rotation direction switching end. A washer device for a vehicle, characterized in that the ring-shaped valve body and the rotary disk are provided so as to be able to rotate relative to each other while moving toward a switching end.
