Abstract

An actuator for automobile comprises a speed reduction mechanism having an input side connected to a motor and an output side provided with an engagement section, a first rotor provided with a predetermined rotational resistance, at least one engagement rod slidably provided in the first rotor, inwardly biased by a spring providing a spring force weaker than the force of the rotational resistance and outwardly projected with an inner end in engagement with engagement section with rotation of the reduction mechanism, and a second rotor with an engagement piece to engage with the free end of the engagement rod with outward projection thereof and connected to a door lock device or the like. When the motor is rotated, the reduction mechanism and second rotor are coupled together directly via the engagement rod. When the motor is stopped, the second rotor and engagement rod are disengaged from each other.
