Abstract
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. Planar guide tracks are formed in the housing lower part to both sides of the piezo actuator. Bearing elements of circular cross-section are arranged between the clamping jaws and the guide tracks. 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.
