BUTTON MECHANISM AND ELECTRONIC DEVICE

PROBLEM TO BE SOLVED: To increase the degree of freedom in a design of a product, while providing excellent operability for a user.SOLUTION: A button mechanism comprises: a switch; a base fitted with a button which is pressed by a user; a movable part which extends from a rear face opposite to a face where the button on the base is located so as to toggle a contact of the switch; and a support part which extends downward from the base so as to support the base. The support part comprises: a first deformation part which is elastically deformed, in response to the pressing operation, in a second direction intersecting a first direction for the movable part to extend; and a second deformation part which is elastically deformed in the first direction in response to the pressing operation. 【課題】ユーザの操作感を良好なものにするとともに、製品の設計の自由度を高めることを目的とする。【解決手段】スイッチと、ユーザによる押圧操作を受けるボタンが取り付けられたベースと、ベースのボタンが位置する面と反対の裏面から伸びて、スイッチの接点を切替える可動部と、ベースから下方に伸びてベースを支持する支持部と、を有する。支持部は、押圧操作に応じて、可動部が伸びる第１の方向と交差する第２の方向に弾性変形する第１の変形部と、押圧操作に応じて、第１の方向に弾性変形する第２の変形部と、を有する。【選択図】図１
