    • A wireless actuator has a structure in which movement of a movable table (2) can be controlled on a base (1) without connecting a power supply cable or a signal cable to the movable table, and even when the plurality of movable tables are provided, each of the movable tables can be independently controlled. The wireless actuator includes a track rail (30, 80), a slide member (31, 81) movable along the track rail, a drive means (4) which is mounted on the slide member and which allows the slide member to travel with respect to the track rail, a radio receiver portion (70) which is mounted on the slide member and which receives a drive control signal for the drive means, a control unit (6) which generates the drive control signal and transmits the drive control signal to the radio receiver portion, and a non-contact power supply means (5) which includes a primary side member (50) provided to the track rail and a secondary side member (51) provided to the slide member and supplies electric power from a side of the track rail to the drive means and the radio receiver portion which are mounted on the slide member.

    • An ultrasonic motor of the invention having a vibrating body 3 and a moving body 11 is supported by a supporting component 7. The rounded lower end of the supporting component is supported in a tapered dent of a supporting base 10. and therefore when a side pressure is applied, it inclines to the supporting base so as to keep stably the contact between the vibrating body and moving body. As a result, a stable motor rotation is always obtained regardless of side pressure. The lead wire 8 is held between a metal elastic element 1 and supporting component, and is pressed against the elastic element. Hence, the lead wire, through contact with the elastic element, is electrically coupled to the common electrode on the upper surface of the piezoelectric element without soldering and without use of conductive resin.
    • 具有振动体3和移动体11的本发明的超声波马达由支撑部件7支撑。支撑部件的圆形下端被支撑在支撑基座10的锥形凹部中,因此当侧压 施加时,它倾斜到支撑基座,以便稳定地保持振动体和移动体之间的接触。 结果,无论侧压如何,始终可以获得稳定的电机旋转。 引线8保持在金属弹性元件1和支撑部件之间,并且被压靠在弹性元件上。 因此,通过与弹性元件接触的引线在压电元件的上表面上电连接到公共电极,而不需要焊接而不使用导电树脂。
