When the contact part 140 comes to the position corresponding to the movement recessed part 203 by the slide of the slide member 2, the hand which bent the operation member 14 may be released. Since the operation member 14 has flexibility or spring property, it returns to its original state when the hand is released.

  In the case where the contact portion 140 is disposed in the moving recess 203, by sliding the slide member 2 as it is, the contact portion 140 is guided so as to automatically bend against the portion formed obliquely. When it comes to a position corresponding to the recess 202, it returns to its original state and is disposed in the latching recess 202.

  When the contact part 140 is disposed in the engaging recess 202, the slide member 2 is stopped at a position where it slides upward. In this state, in the slide member 2, the through hole 22 is disposed at a height position where the through hole 21 is disposed, and overlaps with the operation hole 900 of the upper case cover 90. In this state, the switch push button 911 of the push button unit 91 is exposed through the operation hole 900. At this time, the state shown in FIG. Therefore, the inspection work can be performed by pressing the switch push button 911 directly from the operation hole 900.

  Thus, according to the mounting structure T1 of the push button protection cover 8, the switch push button 911 can be inspected without breaking the push button protection cover 8. Therefore, the push button protection cover 8 is not replaced with a new one after the inspection is completed. In addition, since it is only necessary to slide the slide member 2 without using a dedicated tool or the like at the time of inspection, the work can be performed easily and quickly.

  After completion of the inspection, the side portion of the operation member 14 that is suspended is bent outward and deformed again, and the state of being placed in the engaging recess portion 202 of the contact portion 140 is released. As a result, the slide member 2 is released from the stopped state and slides downward along the guide groove 12. The slide member 2 that has been slid stops in a state where the stopper portion 200 comes into contact with the body portion 11, the contact portion 140 is disposed in the housing recess 201, and the push button protection cover 8 is disposed in the operation hole 900. Thus, the switch push button 911 is protected by the push button protection cover 8 again.

  The push button protection cover 8 can be easily replaced by putting the hand inside the upper case cover 90 to release the engagement state of the lock mechanism portion 13 and rotating it horizontally as shown in FIG. The replacement of the push button protection cover 8 is easier to perform when the slide member is slid in the upward direction, but can be replaced even in the lowered state.

  In the present embodiment, the slide member has been shown to slide in the vertical direction, but this is not limited. For example, the slide member slides in the horizontal direction or moves in the circumferential direction (rotation direction, rotation direction). You can use what you want.
