A wiper system includes a motor bracket to which a wiper motor is fixed, and the motor bracket is fixed to a body with a rubber pad therebetween. A mounting leg made of a hard material extends from a first pivot holder that supports a first pivot shaft, and is directly fixed to the body. Mounting legs made of a hard material extend from a second pivot holder that supports a second pivot shaft, and are directly fixed to the body. According to the wiper system, it is possible to prevent vibration due to a wiper motor from being transferred to the body and a wiper arm from overrunning.

Wiper system

A cylinder 3 in a casing 2 is provided with a first suction chamber 34 and a nozzle part 33 having a suction passage 3d in communication with the first suction chamber 34. In the casing 2. a first piston 4 which is slidably inserted into the first suction chamber 34 and includes a second suction chamber 43 is provided with pushed in a direction of protruding from the first suction chamber 34. Further, in the casing 2, a second piston 5 slidably inserted into the second suction chamber 43 is provided with pushed with less resiliency than with respect to the first piston 4 in a direction of protruding from the second suction chamber 43. At the top part of the casing 2, an operating lever 6 is provided for operating the first and second pistons 4 and 5 to switch between a small suction position that the second piston 5 is embedded in the first piston 4 and a large suction position that the first and second pistons 4 and 5 are embedded in the cylinder 3 and the first piston 4, respectively.
