PURPOSE:To promote efficiency by forming a recessed section on the surface of elastic substances provided with a pair of piezo-electric elements and using as a media for a mover by putting a rotator thereinto. CONSTITUTION:An ultrasonic motor is such that elastic substances 2 and 2' are respectively provided to a pair of piezo-electric elements 4 and 4', and that a recessed section 5 is formed on the surface of elastic substances 2 and 2' to make a construction to secure a rotator 3. The rotator 3 is put into the recessed section 5, and is used as a media for elastic substances 2 and 2' and a mover 1. It is so constituted that elastic substances 2 and 2' perform positive and reverse rotation against the rotator 3 while bringing them into contact with the same rotator 3. Accordingly, it can be used for both linear system and rotary system with high efficiency. |
