ACTUATOR DEVICE AND INPUT DEVICE

摘要

Disclosed, in particular, is an actuator device and input device that can achieve great reaction force, without sacrificing the amount of displacement. The actuator device is provided with an actuator (10) that has one of its ends made to be an anchoring end (14) and the other end made to be a free end (16), and which is bendable when a voltage is applied; and a base member (17) that has an anchoring section (15) that anchors the anchoring end (14) of the aforementioned actuator (10). A protrusion section (60) is provided on the base member (17). When the aforementioned actuator (10) is put in a bent state and a force in the opposite direction of the bending is applied to and deforms the aforementioned free end (16), the actuator (10) will come in contact with the protrusion section (60). The protrusion section (60) will become the fulcrum of deformations, and the reaction force can be made to be greater by the principle of the strength of materials, without sacrificing the amount of displacement.
