## Abstract

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.

## Claims

### Claim 1

A wiper device for a vehicle, comprising:
a main wiping side wiper that wipes a main wiping side of a windshield glass via a main wipe blade that is provided at a main wiper arm that reciprocally rotates between a stopped position and a reversal position;
a secondary wiping side wiper that wipes a secondary wiping side of the windshield glass via a secondary wiper blade that is provided at a secondary wiper arm that reciprocally rotates between a stopped position and a reversal position, wherein the main wiping side wiper is positioned at a driver's seat side, and the secondary side wiping side wiper is positioned at a front passenger's seat side; and
a jetting-out nozzle that is provided only on the secondary wiper arm of the secondary wiping side wiper at the front passenger's seat side and is attached at a position on the secondary wiper arm below both the main wiper blade and the secondary wiper blade in a direction toward the stopped position when such are in the stopped position, and that jets-out cleaning liquid respectively to both (i) a reciprocal rotation outbound side of the secondary wiper blade of the secondary wiping side wiper, and (ii) a reciprocal rotation outbound side of the main wiper blade of the main wiping side wiper at the stopped position.

### Claim 2 (depends on 1)

The wiper device for a vehicle of claim 1, wherein the jetting-out nozzle jets-out the cleaning liquid to a reciprocal rotation inbound side of the secondary wiper blade of the secondary wiping side wiper.
