Abstract
An actuator including a reduction gear that reduces, by a certain reduction ratio, a rotational velocity of an input shaft joined to a rotary shaft of a motor, and transmits the reduced rotational velocity to an output shaft, a first absolute angle encoder that detects a rotational angle of the input shaft, and a second absolute angle encoder that detects a rotational angle of the output shaft.
