Abstract
An input device includes a base member, a motor, a rotation shaft, a worm gear, a first gear, a second gear, an elastic member, a rotor, an angle detection unit, and a controller. The rotation shaft is rotated by the motor. The worm gear is unitarily rotated with the rotation shaft. The first gear is rotatable and engaged with the worm gear. The second gear is coaxial with the first gear. The elastic member generates urging force. The rotor is rotatable relative to the base member, includes a third gear engaged with the second gear, and is rotated by an operator. The angle detection unit detects a first rotation angle of the first gear and a second rotation angle of the second gear. The controller performs drive control for the motor to change a sense of force applied to the operator.
