Claims

[Scope of utility model registration request]

The wiper motor is equipped with a wiper motor that drives the wiper when activated and stops when the wiper returns to the standby position, and a relay switch is intermittently activated on the condition that a predetermined start signal is received to activate the wiper motor intermittently. The signal is provided by an interlocking switch that operates in conjunction with the wiper motor and returns when the wiper returns to the standby position, and a relay that charges a capacitor under the condition that the interlocking switch is activated and after charging is completed. a time constant circuit that starts discharging the capacitor on the condition that the interlock switch and the relay switch are returned to the original state; and a time constant circuit that operates the relay switch and outputs the start signal after a predetermined time after the start of discharging the capacitor. A wiper drive device comprising: a starting circuit for activating a wiper;
