PROBLEM TO BE SOLVED: To provide a vehicular wiper driving device for accurately recognizing that the movement of a wiper is restricted, and performing the inversion control of the wiper. SOLUTION: The vehicular wiper device includes a motor for bidirectionally driving the wiper, a motor current detection means for detecting a current flowing in the motor, and a control means for controlling the motor to invert the driving direction of the motor when the current detected by the motor current detection means exceeds a threshold value. In the vehicular wiper driving device, a supply voltage detection means for detecting a voltage to be supplied to the motor is provided, and the control means changes the threshold value such that the threshold value is reduced in accordance with the reduction of the voltage detected by the supply voltage detection means.
