変トルクワイパ。 In a wiper in which a motor crank arm is cranked by the rotation of a wiper motor with an integrated reduction gear, and the wiper arm, which supports a wiper blade, is oscillated by a link mechanism such as the motor crank arm, a strain gauge is installed at an appropriate position on the wiper arm. A variable torque wiper that is mounted closely together, is provided with a strain amplifier that detects the amount of strain on this strain gauge, and forms a control circuit that uses a solenoid switch to reduce the gear ratio of the reducer in order to increase the wiper drive shaft torque.
