Description

  The present invention is equipped with a special vehicle such as a construction machine or an instrument device such as a water bike, a snowmobile, a ship, or a motorcycle, and operates a push button operation member provided on a case of the instrument device with a fingertip. It is related with the press operation apparatus which operated the apparatus by this.

  As this kind of pressing operation device, for example, Patent Document 1 is known. In this case, as shown in FIG. 7, a push button switch c assembled on the circuit board b in the case a, for example, a push button switch c that is pressed when the timepiece is reset or adjusted, is provided. An operation hole d is formed in the case a, for example, the front panel a so as to face the case, and a pressing operation member e made of, for example, a rubber dustproof member that can be elastically deformed is disposed in the operation hole d to press the push button switch c. It is configured to be operable. The pressing operation member e is formed with a flange portion f for keeping watertight against the operation hole d of the front panel a, and an adhesive g is applied between the flange portion f and the back surface side of the front panel a. By trying to seal.

  By the way, the pressing operation device may be installed at a location exposed to rain water or the like depending on use conditions, and sometimes applied between the operation hole d of the front panel a and the flange portion f of the pressing operation member e. In some cases, the adhesive g may peel off, and it may not be possible to keep watertight between the operation hole d of the front panel a and the pressing operation member e which is a dust-proof member.

For example, Patent Document 2 is known to take this point into consideration. In this case, as shown in FIG. 8, the flange portion f provided on the pressing operation member e between the front panel a and the lower panel h which is an annular holding member disposed on the back side of the front panel a. The peripheral portion is sandwiched and held in a sealed manner. Accordingly, since the peripheral portion of the flange portion f provided on the pressing operation member e is tightly sandwiched between the front panel a and the lower panel h, liquid such as rainwater can be prevented from entering, and the flange can be prevented. Since the peripheral part of the part f is sandwiched and hermetically held, there is an advantage that the assembling workability is also simplified.
