The structure is provided with: a panel (1) having an aperture portion (7a) for assembly of a push-button (2), and an engaging recess (6) furnished to the aperture portion (7a); and a push-button (2) having a positioning projection (5) adapted to engage with the engaging recess (6) when assembled into the panel (1), a switch depression boss portion (4) extending in a direction perpendicular to the panel (1), and a spring portion (3) furnished at a position in opposition to the switch depression boss portion (4). When operated by pushing, the switch depression boss portion (4) rotates about a fulcrum point constituted by the engaged sections of the engaging recess (6) and the positioning projection (5), pushing a switch (9) inside the panel (1), as well as causing the spring portion (3) abutting against the inside wall of the aperture portion (7a) to deflect and impart reaction force in response to rotation of the switch depression boss portion (4). A gap is furnished between the inside wall of the aperture portion (7a) of the panel (1) and the spring portion (3), from a basal portion thereof that connects to the push-button (2) to a spring end portion (3b) thereof, and only the spring end portion (3b) of the spring portion (3) abuts the inside wall of the aperture portion (7a).
