PURPOSE:To effectively spray cleaning water, by forming jet ports which open at a sliding direction side when the convex bead of a wiper blade sliding on a wind shield pane is collapsed, at both sides of the convex bead. CONSTITUTION:In order to remove dirt on the outer surface of a wind shield pane 12, a wiper device 6 is rotated to slide a wiper blade 10, and a washer pump is operated to feed cleaning water W in a washer tank into a water channel 14 through a hose 3. Then, a convex bead 13 integrally incorporated with the base section 11 of the wiper blade 10 is collapsed from its coupling section. As a result, when the wiper blade 10 slides in, for example, the direction A, jet ports 15 at a side corresponding to the direction A are opened to jet cleaning water W while jet ports 15 at the opposite side are closed. |
