To provide a motor-driven type actuator exhibiting improved reliability of a stopper regardless of a space restriction condition to the stopper.
The actuator is provided with a worm wheel attached to an end of an output rotating shaft, a bearing for supporting rotation of the output rotating shaft, a body having a space for housing the worm wheel, a worm gear meshed with the worm wheel, a motor for giving rotational force to the worm gear, and the stopper for regulating a turning region of the worm wheel. The stopper of the actuator is made of a resin material, and is provided with two regulating surfaces in correspondence with a turning regulation angle, and has an air hole exhibiting the damping effect between the regulating surfaces. Thus, the requirement such as reduction of the load to a gear tooth flank or increase of impact energy to the stopper can be coped with, desired torsional rigidity can be set, and reliability of the stopper is improved.
