Claims

[Scope of utility model registration request]

A different liquid filled in multiple wash tanks is pumped out by the wash pump of each wash tank, and the liquid is injected from the wash nozzle to the windshield via piping via a check valve to prevent backflow mixed in each wash hose. In the window washer device, the piping between the check valve for preventing backflow mixing and the washer nozzle is provided with a relief valve having a discharge port for discharging the expanded residual liquid remaining in the piping between the piping, and Prevents liquid from leaking from the washer nozzle due to liquid expansion due to increased pressure of residual liquid in the piping between the check valve for preventing backflow mixing and the washer nozzle, and discharges the expanded liquid out of the piping from the outlet of the relief valve. A window washer device characterized by:
