    • PROBLEM TO BE SOLVED: To simplify a structure of an actuator, and to attain miniaturization and compactness of an installation space, by simplifying and miniaturizing a mechanism for regulating rotation of an element displaced in the straight line direction.SOLUTION: A piston 13 is fixed in a straight line driving part 12. A nut part 21 and a screw part 22 relatively rotate, and the action direction of driving force is converted between the rotational direction and the straight line direction. The piston 13 is arranged inside a case 15. The inner periphery 16a of a piston sliding part 16 fixed to the inside of the case 15, slidably supports the outer periphery of the piston 13. The nut part 21 is displaced together with the piston 13, and the screw part 22 rotates by interlocking with a rotational driving part 11. The piston 13 is slidably arranged in the axial direction of the case 15 to the piston sliding part 16. The axis C2 of the piston 13 and a central position C3 of the inner periphery 16a of the piston sliding part 16 are set to be eccentric with respect to the axis C1 of the screw part 22 and the nut part 21.
    • 要解决的问题:为了简化致动器的结构,并且通过简化和小型化用于调节沿直线方向移位的元件的旋转的机构,实现安装空间的小型化和紧凑化。 解决方案:活塞13固定在直线驱动部分12中。螺母部分21和螺纹部分22相对旋转,并且驱动力的作用方向在旋转方向和直线方向之间转换。 活塞13配置在壳体15的内部。固定在壳体15的内部的活塞滑动部16的内周16a滑动地支承活塞13的外周。螺母部21与活塞13一起位移 螺杆部22与旋转驱动部11联动而旋转。活塞13沿壳体15的轴向滑动配置到活塞滑动部16.活塞13的轴线C2和中心位置C3 活塞滑动部16的内周16a相对于螺纹部22的轴线C1和螺母部21设定为偏心。(C)2013,JPO&INPIT
