  • Patent number: 5086900
    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.

  • Patent number: 4905528
    Abstract: An electric actuator, in which the rotation of the motor is transmitted to the output rod through a pin mounted on a gear connected to motor through the other gears. A stopper is formed on the output rod connected to a door knob, and a pivotal arm mounted on the output rod. A coupling is provided not to transmit the movement of the output rod caused by the door knob, whereby the door is locked or unlocked not only by a remote control, but also by a manual operation of the door knob.
