摘要： A friction material containing at least a rubber-like elastic body is provided between a vibrating stator (2) provided with a piezoelectric element (4) for producing travelling wave and a rotor of an ultrasonic motor. Noise is suppressed and motor capabilities such as driving torque and wear are fairly improved.
