摘要： A small, efficient and stable ultrasonic motor is provided, wherein force is prevented from varying before and after assembly and can be adjusted after assembly without requiring troublesome operations. An electronic apparatus with such a ultrasonic motor is also provided. The ultrasonic motor has a force applying device for applying a force to a vibrating member to be vibrated and to a moving member placed in abutment against the vibrating member to cause a frictional force therebetween so that the moving member is driven by the frictional force. The force applying device comprises a main force applying device for applying a main force and a force adjusting elements for adjusting the force applied by the main force applying device. In one embodiment, the main force applying device is a leaf spring and the force applying elements are slits formed in the leaf spring and strips formed between the slits. Adjustment of the force applied by the leaf spring is performed by removing one or more of the strips.

At least two elastic bodies are connected to opposite ends of the piezoelectric vibrator and are vibrationally driven by the expansion and compression movement of the piezoelectric vibrator. Each of the elastic bodies has at least one groove formed in a surface thereof for converting the expansion and compression movement of the piezoelectric vibrator into torsional vibration so that the elastic bodies generate a combination of longitudinal vibration and torsional vibration. A movable member is connected to the elastic bodies to be frictionally driven by the combination of longitudinal and torsional vibrations generated by the elastic bodies.
