Abstract: PURPOSE: An ultrasonic motor is provided to prevent interference due to a reflecting plate by generating rotational force in a rotor. CONSTITUTION: An output shaft(11) is arranged in the rotary shaft of an ultrasonic motor(10). The output shaft transfers the rotational force which is generated in the ultrasonic motor to the outside. A base supports the output shaft using a bearing in order to rotate an output shaft against a fixing part. A stator(15) has a coaxial cylindrical hole to the central axis of a disk. An engaging board(12) and a spring are fixed to the output shaft which is engaged in each cylindrical hole. The cylindrical hole of a rotor(14) is freely arranged outside the output shaft. The rotor said a spring(13) have elasticity to the rotational axis direction. The stator comprises an elastic member(16), a ground electrode(18), a piezoelectric(19), and a supply electrode(20).
