摘要： An elastic member 43 comprises a crystalline resin. The elastic member is fixed to a piezoelectric element 42 that generates vibration in response to application of an AC voltage, is in contact with a movable body 45 in use, and flexurally vibrates in response to the vibration of the piezoelectric element 42 to drive the movable body 45. The elastic member 43 may have a tooth 43b on an opposite side with respect to a side fixed to the piezoelectric element 42. The crystalline resin may be a poly(aryl ketone) resin or a poly(phenylene sulfide) resin. The piezoelectric actuator has an excellent transmission of flexural vibration. In a case where a displacement expansion element of a displacement-expanding piezoelectric actuator is formed from a crystalline resin, the actuator greatly amplifies an expansion and contraction displacement of a piezoelectric element. In a case where a resonance member of a Langevin transducer is formed from a crystalline resin, the transducer allows the vibration of the surface at a high speed even in application of a low electric current (or a low voltage).

A direction in which the first groove and the second groove face each other intersects a direction in which the support and the moving body face each other, and a biasing direction in which the vibrating body is biased intersects the direction in which the first groove and the second groove face each other and the direction in which the support and the moving body face each other. Accordingly, it is possible to suppress backlash of the moving body with respect to the support.

摘要： An ultrasonic motor includes a vibrator (1), a mobile unit (3), a holding mechanism (4), and a pressing mechanism. The vibrator (1) generates elliptical vibration by degenerating different vibration modes and having a phase difference between the different vibration modes. The mobile unit (3) is configured to be movable relative to the vibrator (1). The holding mechanism (4) holds and fixes the vibrator (1) in a direction substantially parallel to the direction of the relative movement of the mobile unit (3). The pressing mechanism (4) presses the vibrator (1) against the mobile unit (3). The holding mechanism (4) includes an adjustment unit (7a,7b) for adjusting the resonant frequencies of the different vibration modes of the vibrator (1) to substantially match each other when the ultrasonic motor is driven.

摘要： An ultrasonic motor (10) includes a vibrator (50) and an application means (oscillation circuit 80). A first vibrator area (51) and a second vibrator area (52), which form a vibrator (50), include piezoelectric elements polarized in the thickness direction, and fixed portions (30a, 30b) respectively. The oscillation circuit 80 applies an AC voltage to the piezoelectric elements respectively and makes the first vibrator area (51) and the second vibrator area (52) resonate individually in the surface-spreading directions. The ultrasonic motor (10) includes a coupling portion (55) for coupling vibration end portions (23a, 23b) each other and a contact element (60) which is provided on this coupling portion (55). The vibration end portions (23a, 23b) are positions which vibrate respectively in the approaching and separating directions by the resonances of the first vibrator area (51) and the second vibrator area (52) in the surface-spreading directions with respect to the fixed portions (30a, 30b).

摘要： An X-axis driving mechanism section as one of driving sources of a driving apparatus including: a transducer for generating an elliptical vibration on a driving section in response to application of a predetermined frequency voltage signal; a bottom case having a holding section for holding the transducer; a pressing mechanism arranged on the bottom case to press the driving section of the transducer; and a rod relatively driven by the elliptical vibration of the transducer while being pressed by the pressing mechanism and with a moving direction being restricted by a guiding section of the holding member; wherein a weight is fixed to an end portion of the rod. The X-axis driving mechanism section constitutes the driving apparatus which is small and provides a large driving force, is capable of stable driving with higher efficiency without producing audible noise, and can retain the rod position and has high responsiveness with high accuracy.
