PURPOSE: To reduce labor for washing operations by removably mounting an actuator at the mounting part on an eccentric ring rotatably, and guiding by a guide formed apart from the center of rotation, allowing the actuator to make both rotation round its own axis and orbiting with an eccentric shaft as the center, and replacing actuator according to the type of work.
CONSTITUTION: An eccentric ring 27 is dislocated by L from the center is furnished at the tip of an eccentric shaft, which is rotated by a drive motor 12. With a bearing 30 interposed, a mounting boss 28a on the oversurface of an actuator 28 is mounted to this eccentric ring 27 rotatably and removably. A cylindrical guide 31 is formed at the oversurface of this actuator 28 in a position set in radial direction from the mentioned eccentric shaft 22, and a roller 10 of an actuator supporting member 5 will roll. Even though the eccentric shaft 22 rotates, therefore, the actuator 28 makes partial rotary motion under restriction by the guide 31 and also revolves on a circular track of a radius L with the eccentric shaft 22 as the center. Actuator 28 is replaced according to the type of work to accomplish reduction of labor certainly.
