Abstract

PURPOSE: To improve the yielding force and speed, by specifying a bar vibrating body with multiple lugs for a vibrating substance, and by setting the natural frequency of transverse vibration of this lug higher than the vibration frequency of a motor.
CONSTITUTION: A vibrating wave motor is composed of a group of piezoelectric elements 1, an elastic body 21 as a vibrating substance, a moving body 3, a supporting vibration absorber 4 and an anchor body 5. By the travelling vibrating wave of a group of piezoelectric elements 1, etc. the moving body 3 coming into contact with the elastic body 21 is forced to move in the direction of an arrow A or in the reverse direction. At this moment, multiple lugs 21A extended from the bottom of the elastic body 21 are provided in the whole circuit of the elastic body 21. The form of the lug 21A is selected so that the natural frequency of the transverse vibration of the beam of this lug 21A may become higher than the vibrating frequency of the motor. Thus, the travelling wave is not disturbed and its yielding force is not reduced even if the length 1 of the lug 21A is elongated and the pressure W to apply is increased.
