ことを特徴とした進行性波動モータの移動体。 It has a piezoelectric element, a vibrating body to which the piezoelectric element is joined on one plane, and a movable body that is pressed against the other surface of the vibrating body and is frictionally driven by a flexural traveling wave of the vibrating body due to the expansion and contraction movement of the piezoelectric element. In the progressive wave motor, a portion of the movable body that comes into contact with the vibrating body sliding portion or the entire movable body is formed of an engineering plastic containing polyphenylene sulfide as a main component, and silicone oil is applied to the engineering plastic. A moving body of a progressive wave motor comprising:
