Cleaning liquid is easily prevented from adhering to a main wiping side of a windshield glass when a main wiping side wiper, that rotates reciprocally, moves to a reciprocal rotation inbound side. Cleaning liquid is jetted-out from a jetting-out opening of a jetting-out nozzle, but the cleaning liquid does not stick to a reciprocal rotation outbound side of a driver's seat side wiper. Accordingly, the cleaning liquid does not remain without being wiped-off at a driver's seat side of a windshield glass.
