In a wiper device for openable window glass, a pivot shaft having a wiper arm and blade assembly is rotatably held by the window glass. An actuator is fixed to the vehicle body for driving the pivot shaft and is engageable and disengageable with the pivot shaft so as to transmit and interrupt the driving force of the actuator to the pivot shaft. A controller is connected in circuit with the actuator for controlling an operation of the actuator. A switch element is connected in circuit with the controller for generating a first signal when the window glass is opened and a second signal when the window glass is closed. With the wiper device mentioned above, the controller controls the actuator in such a manner that driving the pivot shaft is stopped immediately upon receiving the first signal and is started with a certain time delay after receiving the second signal.
