PROBLEM TO BE SOLVED: To provide a push-button structure free of backlash, which can be manufactured with an inexpensive mold and be assembled easily. SOLUTION: The push-button member 2 is provided with a push-button operating part 2a for switching on and off a switching means 6, a coupling part, a rotating shaft 2d formed at the tip of the coupling part, and a spring part 2e led out toward the direction of the rotating shaft 2d from the push-button operating part 2a. A cover body 7 is provided with a penetrating hole h7 and a rotating bearing C11, housing the rotating shaft 2d of the push-button member underneath, made out to be nearly a U-shaped hole part, and the push-button operating part 2a is housed inside the penetrating hole h7, so arranged as not to fall off from the inside of the rotating bearing C11 by a circuit board 5. Further, the spring part 2e has at its tip a protruded part P1 protruding toward the circuit board 5, which comes in contact with the surface of the circuit board 5, while the push-button member 2 is pressed to the rear face of the cover body 7 by the spring part 2e. |
