PURPOSE:To aim at simplifying the structure of a drive device by disposing a plurality of ultrasonic motors for driving apparatus installed on an automobile, and by connecting at least one oscillator to the motors through a selector switch or the like so that the plurality of the ultrasonic motors is operated only by one oscillator. CONSTITUTION:A plurality of ultrasonic motors 6 through 9 are respectively made into contact with several kinds of onboard apparatus such as power windows 2, wipers 3, mirrors 4 and lights 5, the like which are installed on an automobile 1, and are connected to a control device C through the intermediary of lead wires, respectively. In this control device C, the motors 6 through 9 are connected to an oscillator 11 through a selector switch 10. With this arrangement, a movable contact 10a in the selector switch 10 is rotated so as to transmit an oscillating output to a desired one of the motors 6 through 9 from the oscillator 11 so as to drive a desired one of the onboard apparatus 2 through 5. |
