If it is screwed, the light emitting member 12, the waterproof cover 13, and the light diffusing plate 14 are sandwiched and fixed between the control board 17 and the front case 2 from the front and rear, and the setting of the calling button 6 is completed.

  In the calling button 6 installed as described above, the waterproof cover 13 has the folded portion 29 sandwiched from the front and rear by the peripheral portion of the insertion hole 42 of the front case 2 and the step portion 26 of the light emitting member 12. It has become. In addition, the outer edge portion 13 a of the waterproof cover 13 is sandwiched from the front and rear by the rear end of the light emitting member 12 (the front end of the rear portion 25) and the light diffusion plate 14 behind the folded portion 29. The waterproof cover 13 covers the front side of the control board 17 in such a state that the waterproof cover 13 is sandwiched between the outer peripheral edges, and from the gap between the operation member 11 and the light emitting member 12 to the rear side of the operation member 12. Even if water has infiltrated, further intrusion to the control board 17 side beyond the waterproof cover 13 and thus to the inside of the main body case is prevented. Further, since the inclined surface 32 as described above is formed from the raised portion of the waterproof cover 13 to the outer edge portion 13a, it is not the inclined surface 32 but a vertical surface (that is, only the raised portion protrudes forward). The space between the waterproof cover 13 and the operation member 11 or the light emitting member 12 in the inclined surface 32 portion is narrower than that of the structure having the structure.

  In the calling button 6, when the operation surface 11 a of the operation member 11 is pushed in, the waterproof cover 13 is pressed in the pushing direction (backward) by the operation protrusion 22, and the raised portion of the waterproof cover 13 is bent backward. The switch 16 is operated. When the push-in operation is released, the waterproof cover 13 returns to the state before deformation by its own elastic force, and the operation member 11 is pushed out along with the return and returns to the position before the push-in operation. The positioning protrusion 33 of the waterproof cover 13 is fitted into the positioning recess 43 of the front case 2 and the engagement rib 23 of the operation member 11 is engaged with the engagement recess 31 of the waterproof cover 13.

The outer edge portion 13a of the waterproof cover 13 is sandwiched from the front and rear by the rear end of the light emitting member 12 (the front end of the rear portion 25) and the light diffusion plate 14 behind the folded portion 29. Yes. And the waterproof cover 13 covers the front side of the control board 17 in the state clamped by the outer peripheral edge part in this way. Therefore, even if water enters the rear side of the operation member 12 from the gap between the operation member 11 and the light emitting member 12, it further passes the waterproof cover 13 to the control board 17 side, and further to the inside of the main body case. Intrusion is prevented and high waterproofness can be exhibited.

  Moreover, since it is set as the inclined surface 32 which inclines toward the back side toward the radial direction outer side from the protruding part of the waterproof cover 13 to the outer edge part 13a, compared with what was made into the vertical surface instead of the inclined surface 32. The space between the waterproof cover 13 and the operation member 11 or the light emitting member 12 in the inclined surface 32 is narrow. Therefore, the amount of water that can enter the front surface side of the waterproof cover 13 from the gap between the operation member 11 and the light emitting member 12 can be reduced, and further waterproofness can be improved.

  Further, the positioning protrusion 33 of the waterproof cover 13 is fitted into the positioning recess 43 of the front case 2, and the engagement rib 23 of the operation member 11 is engaged with the engagement recess 31 of the waterproof cover 13. Therefore, it is possible to prevent the operation member 11 from rotating about the front-rear direction in the front portion 24 of the light emitting member 12.
