Abstract:
1. An input device comprising: an actuating member formed of a synthetic material and comprising: detecting elements that detect elastic deformation of the deformable parts and that are configured such that electrical resistance of the detecting elements changes according to amount of strain in the deformable parts in an expansion direction and a contraction direction; a lower case defining a recess and including a bottom surface and a plurality of supporting surfaces raised from the bottom surface, the bottom surface and the plurality of supporting surfaces disposed in the recess; and an upper case disposed on the lower case and having a lower surface; wherein when the actuating member is mounted to the lower case, the thick-walled parts and the deformable parts are received in the recess with the thick-walled parts abutting against the plurality of supporting surfaces of the lower case and the lower surface of the upper case such that the thick-walled parts of the actuating member are sandwiched between the lower surface of the upper case and the plurality of supporting surfaces of the lower case, wherein the deformable parts have base ends located on the side of the operating protrusion, and tips located apart from the operating protrusion, and the operating protrusion is provided with protruding parts extending onto the deformable parts over the base ends, and wherein the actuating member is provided with a plurality of terminals electrically connected to the detecting elements, and the plurality of terminals appear on side surfaces of the lower case.
