Claims

[Scope of utility model registration request]

In a sonic motor that transmits a sound wave from a vibrator 1 to a rotor 4 via a vibrating piece 3 and moves the rotor 4 in a direction substantially perpendicular to the vibration direction of the vibrator 1, the vibrating piece 3 is characterized in that it has a large number of fibrous sliders 7 made of an elastic body or plate-shaped sliders 7 whose surfaces are arranged substantially perpendicular to the direction of movement of the rotor 4. sonic motor.
