The first end 55a is connected to the inner surface 41a of the accommodation chamber 41 formed by the side wall 46. The first end 55a is welded to the side wall 46, for example. The first end 55a may only contact the side wall 46.

The second end 55b is an end of the partition plate 55 in the positive direction of the X axis. The second end 55b is separated from the inner surface 41a of the storage chamber 41 formed by the side wall 46 in the positive direction of the X axis. The second end 55b is located above the first end 55a in the vertical direction (Z-axis direction). Further, the second end 55b is separated from the upper wall 44, the lower wall 45, and the side walls 46 and 47.

The partition plate 55 extends between the first end 55a and the second end 55b. In the present embodiment, the partition plate 55 linearly extends obliquely upward from the first end 55a to the second end 55b. In other words, the partition plate 55 extends upward as it moves away from the inner surface 41a of the accommodation chamber 41 to which the first end 55a is connected. The partition plate 55 may extend, for example, in a curved shape between the first end 55a and the second end 55b.

As shown in FIG. 2, the side end portion 55c is an end portion of the partition plate 55 in the positive direction of the Y axis. The side end portion 55c is connected to the inner surface 41a of the accommodation chamber 41 formed by the back wall 43. The side end portion 55c is welded to the back wall 43, for example.

Further, in the Y-axis direction, the side end 55c is separated from the upper hole 51 in the positive Y-axis direction, and the side end 55d is separated from the upper hole 51 in the negative Y-axis direction. Therefore, the partition plate 55 is located below the upper hole 51.

A liquid receiver 56 is provided between the substrate 22 of the storage chamber 41 and the upper hole 51 by the drip-proof portion 24. The liquid receiver 56 is a space that is formed (defined) by the back wall 43, the side wall 46, the partition plate 55, and the operation panel 21 that closes the storage chamber 41, and is opened upward. The liquid receiver 56 is open toward the upper hole 51. The liquid receiver 56 can store the liquid until the liquid surface reaches the second end 55b.

The discharge hole 53 is located above the first end 55a. Further, the discharge hole 53 is located below the second end 55b in the vertical direction. Therefore, the discharge hole 53 connects the liquid receiver 56 and the outside of the box 23.

The wiring 25 has, for example, a plurality of bundled wirings, supplies electric power to the board 22, and transmits and receives signals between the board 22 and the control device of the elevator 1. The wiring 25 is not limited to this example.

The wiring 25 is connected to the substrate 22 and extends to the outside of the box 23 through the upper hole 51. The wiring 25 is laid outside the box 23, for example, to a duct above the car 10. Therefore, the wiring 25 is easily laid without detouring below the box 23, and the workability of laying the wiring 25 is improved. The operation panel 13 may have other wiring connected to the substrate 22 and extending to the outside of the box 23 through the pilot hole 52.

The wiring 25 has a first portion 61, a second portion 62, and a third portion 63. The first portion 61, the second portion 62, and the third portion 63 are portions of the wiring 25 that are virtually divided in the direction in which the wiring 25 extends and are connected to each other.

The first portion 61 is a part of the wiring 25 that passes through the upper hole 51 and extends substantially vertically. The first portion 61 is located between the first end 55a and the second end 55b of the partition plate 55 in the X-axis direction. The first portion 61 is located above the partition plate 55.

The second portion 62 is a part of the wiring 25 that is connected to the substrate 22 and extends substantially vertically. The second portion 62 is separated from the first portion 61 in the X-axis direction and is located between the second end 55b of the partition plate 55 and the side wall 47.

The upper end portion 62a of the second portion 62 is located higher than the lower end portion 61a of the first portion 61 in the vertical direction. The lower end 61 a of the first portion 61 is located below the second end 55 b of the partition plate 55 in the up-down direction, and is located inside the liquid receiver 56. The lower end 61 a of the first portion 61 may be located outside the liquid receiver 56.

The third portion 63 extends between the lower end 61 a of the first portion 61 and the upper end 62 a of the second portion 62. In other words, the third portion 63 extends obliquely upward from the lower end 61a of the first portion 61 to the upper end 62a of the second portion 62. The third portion 63 extends, for example, along the partition plate 55.

The third portion 63 is connected to the lower end portion 61a of the first portion 61 and the upper end portion 62a of the second portion 62, so that the wiring 25 has a substantially Z shape (N shape). Is laid. In other words, the wiring 25 is laid so as to be folded back at the lower end 61 a of the first portion 61 and the upper end 62 a of the second portion 62. The laying of the wiring 25 is not limited to this example.

The fixing portion 26 is provided in the accommodation chamber 41 and fixes the wiring 25 laid as described above at least at one place. By fixing the wiring 25, the fixing portion 26 suppresses deterioration of the wiring 25 due to kink. Each of the fixing portions 26 has, for example, a bracket 71 and a binding band 72.

The bracket 71 is fixed to, for example, the inner surface 41a of the housing chamber 41 formed by the back wall 43. One binding band 72 fixes the first portion 61 of the wiring 25 to one bracket 71. The other binding band 72 fixes the second portion 62 of the wiring 25 to the other bracket 71. The fixing portion 26 is not limited to this example, and the wiring 25 may be fixed to the inner surface 41a of the housing chamber 41 with an adhesive, for example.

The grommet 27 is attached to the first portion 61 of the wiring 25 and closes the gap between the first portion 61 and the edge of the upper hole 51. The gap between the first portion 61 and the edge of the upper hole 51 may be closed with, for example, a synthetic resin, or the diameter of the first portion 61 and the diameter of the upper hole 51 may be close to each other to minimize the gap. You may be made into.

As shown by the arrow in FIG. 3, for example, water W in the hoistway of the elevator 1 may enter the accommodation chamber 41 from the upper hole 51. Water W is an example of a liquid. The water W flows downward, for example, along the first portion 61 of the wiring 25.

Since the third portion 63 of the wiring 25 extends obliquely upward, the water W drops downward from the lower end portion 61 a of the first portion 61. The partition plate 55 receives the water W falling from the upper first portion 61 and the water W directly falling from the upper upper hole 51.

Since the partition plate 55 is located between the substrate 22 and the upper hole 51, it receives the water W and prevents the water W from reaching the substrate 22. In this way, the partition plate 55 receives the upper water W and restricts the water W from going toward the substrate 22.

The partition plate 55 extends obliquely downward from the second end 55b toward the first end 55a. Therefore, the water W received by the partition plate 55 flows along the partition plate 55 toward the first end 55a. That is, the water W flows away from the gap between the side wall 47 and the second end 55 b that can drop onto the substrate 22.

The water W is discharged to the outside of the box 23 through the discharge hole 53 located above the first end 55a. In this way, the discharge hole 53 causes the water W received by the drip-proof portion 24 to flow out of the box 23. The water W received by the drip-proof part 24 may be evaporated and discharged to the outside of the box 23 from the upper hole 51 and the lower hole 52, for example.

The discharge hole 53 may be omitted from the box 23. In this case, the water W received by the partition plate 55 is stored in the liquid receiver 56. The grommet 27 reduces the amount of water W entering the storage chamber 41. Therefore, the amount of water W that reaches the second end 55b is suppressed from being stored in the liquid receiver 56, and the water W is discharged from the upper hole 51 and the lower hole 52 to the outside of the box 23 by evaporation. It

In the operation panel 13 according to the first embodiment described above, the box 23 is provided with the upper hole 51 communicating with the housing chamber 41 on the upper surface 44a. The drip-proof part 24 is provided between the substrate 22 and the upper hole 51, and is configured to receive the upper water W and restrict the water W from flowing toward the substrate 22. The wiring 25 is connected to the substrate 22 and extends to the outside of the box 23 through the upper hole 51. As a result, the wiring 25 can be laid upward, and the workability of laying the wiring 25 is improved. Furthermore, since the water W entering the accommodation chamber 41 from the upper upper hole 51 is received by the drip-proof portion 24, the water W is prevented from reaching the substrate 22, and the substrate 22 is protected from the water W.

The drip-proof part 24 is located between the substrate 22 and the upper hole 51, and is separated from the first end 55a connected to the inner surface 41a of the accommodation chamber 41 and from the inner surface 41a, and from the first end 55a. Also has a partition plate 55 extending between the second end portion 55b and the second end portion 55b. As a result, the water W received by the partition plate 55 flows toward the first end 55a. The water W received by the partition plate 55 is stored in the drip-proof portion 24 until reaching the amount exceeding the second end portion 55b, and is restricted from heading to the substrate 22. As a result, the water W is prevented from reaching the substrate 22, and the substrate 22 is protected from the water W.

The box 23 is provided with a discharge hole 53 that allows the storage chamber 41 and the outside of the box 23 to communicate with each other and allows the water W received by the drip-proof portion 24 to flow out of the box 23. Thereby, the water W is suppressed from accumulating in the accommodation chamber 41, and the water W is suppressed from reaching the substrate 22.

The first portion 61 of the wiring 25 is passed through the upper hole 51. The upper end 62a of the second portion 62 is located above the lower end 61a of the first portion 61. The third portion 63 extends between the lower end 61 a of the first portion 61 and the upper end 62 a of the second portion 62. That is, the third portion 63 is a portion that is folded back upward from the lower end portion 61 a of the first portion 61. When the water W adheres to the third portion 63, the water W flows along the third portion 63 toward the lower end 61 a of the first portion 61. Thereby, for example, the water W that has entered the accommodation chamber 41 from the upper hole 51 is suppressed from reaching the third portion 63 of the wiring 25, and further reaches the substrate 22 through the third portion 63. Is suppressed.

FIG. 4 is an exemplary front view schematically showing a part of the operation panel 13 according to the modified example of the first embodiment. In the modified example of the first embodiment, the partition plate 55 extends in a substantially L shape between the first end 55a and the second end 55b.

The partition plate 55 has a first extension 81 and a second extension 82. The first extending portion 81 extends from the first end portion 55a of the partition plate 55 in the positive direction of the X axis. The second extending portion 82 extends downward from the second end portion 55b of the partition plate 55 and is connected to the end portion of the first extending portion 81 in the positive direction of the X axis.

The first extending portion 81 of the partition plate 55 receives the water W falling from the upper first portion 61 and the water W directly falling from the upper hole 51. The water W received by the first extension 81 is stored in the liquid receiver 56 and is discharged to the outside of the box 23 by the discharge hole 53.

Since the partition plate 55 is formed in a substantially L shape, the liquid receiver 56 has a large volume and can store more water W. Further, since the second extension 82 extends upward from the first extension, the first extension 81 extends horizontally or extends downward as it moves away from the first end 55a. However, the water W is restricted from moving toward the substrate 22.
