    Abstract: A position detection device detects a current positon of a operation member among positions including a predetermined position and includes a detection system that includes a part to be detected and 3N magnetic sensors S. The operation member can move to the positions in N (≥3) different directions from the predetermined position. Movement of the operation member between the predetermined position and another position cause outputs from three of the magnetic sensors to be switched. The magnetic sensors of which outputs are switched by a movement of the operation member between the predetermined position and a first position are all different from the magnetic sensors of which outputs are switched by a movement of the operation member between the predetermined position and a second position.

    Abstract: An input device includes a knob, a detector, an electromagnetic brake, an elastic member, and a controller. The detector detects a rotation angle of the knob. The electromagnetic brake regulates rotation of the knob. The elastic member is provided between the knob and the electromagnetic brake. When the current position of the knob in the circumferential direction is not the target position for rotation regulation of the knob, the controller does not activate the electromagnetic brake. When the current position of the knob in the circumferential direction is the target position for rotation regulation of the knob, the controller determines whether to regulate rotation of the knob based on a rotation direction of the knob, or on a rotation angle of the knob that shifts from the holding position of the knob in the circumferential direction due to deformation of the elastic member.
