Actuator of vehicle door lock device

摘要

An actuator of a vehicle door lock device, which includes an output shaft adapted at one end to be coupled with to a lock lever of the lock device, a sector arm for rotating the output shaft, a reversible motor for rotating the sector arm around said output shaft through speed reduction gears and a plastic-made housing for accommodating the output shaft, the sector arm and the reversible motor. The sector arm has, on an inner surface of its outer arc-shaped flange, an inner toothed portion which meshes with a final gear of the reduction gears and an arc hole centering the output shaft. An intermediate shaft for supporting the final gear is arranged in parallel with the output shaft and projects through the arc hole.
