Abstract: A rotation angle detection device includes a lever, a cylindrical part, a magnet, and a magnetic sensing element. The lever includes a base and a shaft projecting in the direction of the rotation axis of the base and integrated with the base. The cylindrical part has a first end close to or in contact with the base, and a second end opposite to the first end and farther from the base than the first end. The shaft is inserted in the cylindrical part and is rotatably supported by the cylindrical part. The magnet is attached to the end of the shaft. The magnetic sensing element faces the magnet with a predetermined gap therebetween.

Abstract: The electrostatic detection sensor has a first electrode, a second electrode, and a third electrode. A controller connects the first electrode and the second electrode, and applies a first drive voltage thereto to obtain a first intensity. The controller applies a second drive voltage to the first electrode while keeping the second electrode and the third electrode at a ground potential to obtain a second intensity. The controller applies a third drive voltage to the third electrode while grounding the first electrode to the ground potential and keeping the second electrode open to obtain a third intensity. Then, the controller determines whether an object is approaching based on first, second, and third computed values which are computed temporal changes in the first, second, and third intensities, respectively.

Abstract: A rotation angle detection device of the present disclosure includes, a rotating body having a cylinder and configured to rotate with rotation of a rotating shaft coupled to an inside of the cylinder, an engagement protrusion provided inside of the cylinder of the rotating body and protruding in a first direction serving as a direction in which the rotating shaft extends, an elastic member mounted to the engagement protrusion and having an elastic holding part, a case having a rotation supporting part that rotatably supports the rotating body, and a rotation angle detector configured to detect a rotation angle of the rotating body. A predetermined gap is provided between the rotation supporting part of the case and an outer periphery of the cylinder of the rotating body. A fitting part protruding in a second direction perpendicular to the first direction is formed on an outer periphery of the engagement protrusion. The elastic member is mounted to the engagement protrusion so that the elastic holding part can be elastically deformed in a rotating direction of the fitting part.
