ことを特徴とするワイパー駆動装置。 The wiper motor is provided with a wiper motor that drives the wiper when activated and stops when the wiper returns to the standby position, and the wiper is intermittently activated by intermittently giving a start signal to the wiper motor on the condition that a predetermined start signal is received. and a comparator having a capacitor connected to its input terminal, the interlocking switch being operated in conjunction with the wiper motor and returning when the wiper returns to the standby position, and the actuation of the interlocking switch. Discharge the charge in the capacitor on the condition that the interlocking switch returns, and start charging the capacitor on the condition that the interlocking switch returns, and when the potential of the capacitor rises to a predetermined value or more, output a start signal from the output terminal of the comparator. A wiper drive device characterized by being provided with a time constant circuit.
