Outline of Final Research Achievements	Ultrasonic motors are used for a variety of purposes like linear motion drive and rotational drive, and are usually designed and developed specifically for its intended method of use. Therefore, the development of an ultrasonic motor takes up a lot time and cost. In this study, we propose a new structure of standing-wave type ultrasonic motor and try to develop a motor that is able to perform both linear motion drive and rotational drive. The objective of this study is to verify the performance of this motor and further miniaturize the motor. The effectiveness of the motor is confirmed from experimental results and an analysis result.
