The switch structure (82, 83, 123, 124) for controlling the driving of the device includes an operation unit housing (61, 122) held by a user and a switch provided inside the operation unit housing (61, 122). A switch operating unit (87) including a contact (90, 91) and a pressure receiving unit (97, 136) pressed by the user, and operating the switch contact (90, 91) between an open state and a closed state. , 132). Further, the pressure receiving portion (97, 136) is supported to be tiltable with respect to the operation portion housing (61, 122) about a tilt center (O) inside the operation portion housing (61, 122), and In the state where the pressure receiving portion (97, 136) is tilted and the pressure receiving portion (97, 122) is in a neutral position where the pressure receiving portion (97, 122) is not tilted, the user can move the tilt center (97, 136) of the pressure receiving portion (97, 136). Supporting portions (88, 133) for supporting the pressure receiving portions (97, 136) so as to be able to be pushed in the direction of O) are provided.機器の駆動を制御するスイッチ構造（８２，８３，１２３，１２４）は、使用者により保持される操作部ハウジング（６１，１２２）と、前記操作部ハウジング（６１，１２２）の内部に設けられるスイッチ接点（９０，９１）と、前記使用者により押圧される受圧部（９７，１３６）を備え、開状態と閉状態との間で前記スイッチ接点（９０，９１）を操作するスイッチ操作部（８７，１３２）とを備える。また、前記受圧部（９７，１３６）を前記操作部ハウジング（６１，１２２）に対して前記操作部ハウジング（６１，１２２）の内部の傾動中心（Ｏ）を中心に傾動可能に支持し、かつ、前記受圧部（９７，１３６）が傾動した状態及び前記受圧部（９７，１２２）が傾動していない中立位置の状態で、前記使用者が前記受圧部（９７，１３６）の前記傾動中心（Ｏ）の方向に押し込み可能に前記受圧部（９７，１３６）を支持する支持部（８８，１３３）を備える。
