A movement mechanism includes: a case; a moving portion movable with respect to the case; and a support member that links the case and moving portion together and supports the moving portion so as to be movable with respect to the case. The support member has a plurality of pairs of first support portions and a plurality of pairs of second support portions, each of which is elastically deformable, has a plate-like shape, and extends between the case and the moving portion. The first support portions and second support portions are respectively placed on a first side and a second side in a moving direction of the moving portion so as to be symmetric with respect to the moving portion in plan view.

Movement mechanism and input device

An input device is characterized in that in a first stroke region in which an operation panel is pushed during a touch operation, a first reaction force that occurs by pushing the operation panel is generated by the first elastic portion. In a second stroke region including a stroke longer than in the first stroke region and a stroke for performing a push operation, a second reaction force that occurs by pushing the operation panel is a resultant force generated by a first elastic portion and the push switch. In the vicinity of a boundary between the first stroke region and the second stroke region, the amount of change in the first reaction force with respect to a stroke length is less than the amount of change in the second reaction force with respect to a stroke length.

According to the method of manufacturing a surface acoustic wave device of the invention, since a conductor layer is formed on electrode sections in a state where the entire regions of inter digital transducer and reflectors are covered with an insulating film, the inter digital transducer and the reflectors are protected by the insulating film during formation of the conductor layer. As a result, it is possible to obtain a highly efficient surface acoustic wave device with no sticking of foreign matters to the inter digital transducer and the reflectors.
