A vibration actuator is capable of bringing a vibration body into press contact with a driven body stably for an extended period while reducing obstruction of excitation of vibration in the vibration body by the pressing force. The driven body is in contact with the vibration body by a pressing force given by a pressing member. A vibration isolation member is arranged between the vibration body and the pressing member. The vibration body and the driven body move relatively by vibrations in first and second vibration modes that are excited in the vibration body by applying alternating voltage to a piezoelectric device on the vibration body. Face pressure that acts on the piezoelectric device by the pressing force from the pressing member in first and second areas that respectively include nodal lines in the first and second vibration modes and their vicinities is higher than that in other areas.

The invention comprises a piezo motor with a U-shaped housing lower part and a mounted cover. The piezo actuator is mounted between two clamping jaws.

Thrust pieces are braced between the housing cover and the bearing elements, which thrust pieces press the bearing elements against the clamping jaws. Here, the thrust pieces together with the guide tracks of the housing lower part form V-shaped guides.
