ABSTRACT:
There is disclosed an actuator with a clutch mechanism in which a shaft device for operating an external mechanism is formed with threads thereon so as to be engaged with or disengaged from threads at inner surfaces of a plurality of collet type chuck members. The collet type chuck members are fitted into a member having outer teeth thereon, a line of magnetic force of an electromagnetic solenoid selectively acts upon pull-wedge members outside the collet type chuck members, whereby the collet type chuck members are engaged with or disengaged from the threads of the shaft device, and in the engaged condition, the member having outer teeth thereon is driven to rotate by a driving device, whereby the shaft device inside the member having outer teeth thereon is caused to be moved back and forth in a linear movement.
