Abstract
An actuator includes a yoke having an inner circumferential surface; an armature including a rotary shaft provided inside the yoke; a drive shaft configured to be driven to rotate when receiving a rotating force from the rotary shaft; a cylindrical first housing; a second housing relatively movable with respect to the first housing; a speed reduction gear part is disposed between the rotary shaft and the drive shaft; and a driven member is connected to the drive shaft for moving in an axial direction of the drive shaft in response to rotation of the drive shaft. The yoke is disposed within the first housing and a damper member is disposed between the first housing and the speed reduction gear part.
