Abstract
The actuator includes a control unit configured to allow a first control capable of driving a drive part with a first driving force and a second control capable of driving the drive part with a second driving force which is stronger than the first driving force, a moving part configured to move in a predetermined direction, an elastic member configured to receive at least one of the first driving force and the second driving force from the drive part and to supply a force for the moving part to move to the moving part, and a detection unit configured to supply a detection signal for detecting a stop of the drive part to the control unit, in which the control unit performs the second control when a stop of the drive part is detected after performing the first control.
