Abstract: PURPOSE:To make the device small and the weight light by providing an ultrasonic wave motor having a rotor fixed to one end of a cylinder of a rotary guide coaxial with a stator and driven by an external power supply to the device. CONSTITUTION:A rotor 52 and a stator 51 are arranged coaxially in contact with each other, a voltage is applied to a piezoelectric body 512 to vibrate the stator 51 in axial direction. A vibration in terms of a travelling wave travelling as lapse of time is excited in the circumferential direction of the stator 51, an elastic body 511 is resonated to the travelling wave to drive the rotor 52 in contact with the elastic body 511 of the stator 51 axially. In this state, an ultrasonic motor 5 is driven by an external power supply to drive a rotary guide 1 by 90 deg.C around the rotary shaft 6. Thus, the high frequency power energy inputted to the outside of the guide 7a is transmitted to the guide 7d with the guide 3b connecting to the guide 7a. Thus, the size is made small and the weight is made light.
