Beschreibung
Zusammenfassung:	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.
