Abstract
An input apparatus includes a case, an operation body stored rotatably in the case, a magnetic body fixed to the operation body, a magnet provided around the operation body, a magnetic detection element for detecting a magnetic flux from the magnetic body, and a frame for retaining the case. The magnetic detection element faces the operation body with a predetermined space therebetween. The frame includes depression sections for causing the magnetic detection element to elastically contact the lower surface of the case. This input apparatus can accurately detect a rotation angle.
