ABSTRACT:
In the electric actuator of the present invention, the power converting mechanism is provided for converting the rotary power of the motor into linear power of the driven member, which needs no special component part. Therefore, in comparison with the prior art power converting mechanism, it is advantage in that the scale of speed reduction and the stroke can be freely determined, with remarkably reduced number of parts and in low cost. The electric actuator according to the present invention is also provided with the improved clutch device employing the engagement of the weight and the recessed portion for secure transmission of the rotary power of the motor, resulting in full utilization of the capacity of the motor in simplified structure.
