PROBLEM TO BE SOLVED: To provide a wiper device capable of continuing injection of cleaning fluid until a wiper blade reaches a predetermined position, and rotating the wiper blade a predetermined number of times after the completion of the cleaning fluid.SOLUTION: A wiper control circuit 22 calculates positions of wiper blades 28 and 30 on a windshield 12 from a rotation angle of an output shaft 32 detected by a sensor provided to a speed reduction mechanism 52 of a wiper motor 18, and, based on the calculated positions, causes a washer motor 56 to operate until the wiper blades 28 and 30 turn reciprocatively between a lower inversion position P2 and an upper inversion position P1 a first predetermined number of times and reach the lower inversion position P2. Also, the wiper control circuit 22 causes the wiper motor to operate until the wiper blades 28 and 30 turn reciprocatively from the lower inversion position P2 a second predetermined number of times and reach the lower inversion position P2. |
