Abstract
A multi-directional input device includes an operating shaft capable of rotating around a central axis thereof and tilting in multiple directions from the central axis; a rotating body rotating together with the operating shaft to sequentially connect or disconnect a slide contact and a fixed contact; and a plurality of horizontal push switches operable by tilting the operating shaft. The engaging surface between the operating shaft and the rotating body forms a curved surface having both arc element and noncircular element. The operating shaft and the rotating body are always in contact with each other in a large area. Thus, in both tilting and rotating operation, even an extended period of use causes less abrasion.
