WIPO Patent Application WO/2023/189047
Kind Code:
A1
Abstract:
A washer tank (18) for storing a washer liquid to be supplied to a front ejection device (16) and a rear ejection device (17) is made of a transparent or translucent container, and comprises an inclined surface (19A) that inclines from a bottom surface (19D) of a first container part (19) to a top surface (19C). Therefore, when the height of a liquid level (L1, L2) of the washer liquid changes inside the washer tank (18), a front edge (P1, P2) of the liquid level (L1, L2) moves in the front-rear direction along the inclined surface (19A). This enables an operator to confirm a remaining amount (E1, E2) of the washer liquid merely by viewing and confirming the position of the front edge (P1, P2) of the liquid level (L1, L2) appearing on the inclined surface (19A) of the first container (19) from above.
