Abstract
An input device has a housing having an operation hole formed therein, an operation member supported in a slidably moving manner in multi-directions within the operation hole, and at least two magnetic sensors, arranged at a periphery of the operation member, for detecting change in magnetic property by displacement of the operation member. The operation member includes a holder having a circular ring-shaped magnet incorporated in a fit-in hole and a central push button having a disc plate made of magnetic material integrated at a lower surface. The central push button is fitted in the circular ring-shaped magnet to adsorb, in a separable manner, the disc plate to the circular ring-shaped magnet and position-regulate the central push button.
