Abstract

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.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 142 words
An actuator for an automobile having a motor comprising: a speed reduction mechanism having an input side connected to said 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 said first rotor, inwardly biased by a spring providing a spring force weaker than the force of said resistance and outwardly projected with an inner end in engagement with said engagement section with rotation of said mechanism; and a second rotor with an engagement piece to engage with an outer end of said rod and connected to a door lock device; said mechanism and said second rotor being coupled together directly via said rod when said motor is rotated, said second rotor and said rod being disengaged from each other when said motor is stopped.
Claim 2
Dependent Claim 142 words
An actuator for an automobile having a motor comprising: a speed reduction mechanism having an input side connected to said 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 said first rotor, inwardly biased by a spring providing a spring force weaker than the force of said resistance and outwardly projected with an inner end in engagement with said engagement section with rotation of said mechanism; and a second rotor with an engagement piece to engage with an outer end of said rod and connected to a door lock device; said mechanism and said second rotor being coupled together directly via said rod when said motor is rotated, said second rotor and said rod being disengaged from each other when said motor is stopped.
