An antenna board 20 having an antenna 21 for wireless communication between a wireless device and a communication device is held in the drain cap 10. Note that the box 1 is installed with the back surface 6 fixed to a wall or the like as an installation surface.

Here, the drain cap 10, which is the main part of the present invention, will be explained.
The drain cap 10 includes a vertically long cylindrical antenna holding part 11, a flange part 12 protruding radially outward from the upper end of the outer periphery of the antenna holding part 11, and a collar part 12 extending further upward from the upper end surface of the antenna holding part 11. It is a synthetic resin member that is integrally provided with a mounting portion 13 that protrudes from the top.

The antenna holding portion 11 is formed to have a longer vertical length than the antenna substrate 20, and the antenna holding portion 11 is provided with holding grooves 14, 14 that open on the upper end surface. In each holding groove 14, the length when viewed from above is approximately the same as the left-right length of the substrate 22 (the length in the short direction of the substrate 22), which will be described later, and the width when viewed from the top is The depth in the vertical direction is approximately the same as the vertical length of the substrate 22 (the length of the substrate 22 in the longitudinal direction). Further, at both ends of each holding groove 14 in the length direction when viewed from above, accommodating portions 15 capable of accommodating connecting portions 24 to be described later are provided, respectively. The two holding grooves 14, 14 are provided such that their central portions are perpendicular to each other when viewed from above.

The mounting portion 13 is formed into a cylindrical shape with a diameter substantially the same as the diameter of the round hole 7, and holding grooves 14, 14 are located within the mounting portion 13 on the upper end surface of the antenna holding portion 11. Further, the mounting portion 13 is provided with locking claws 18, 18 that lock onto the opening edge of the round hole 7 (bottom surface 4 of the box body) when the mounting portion 13 is attached to the box body as described later. Furthermore, the mounting portion 13 is provided with notches 19, 19 cut out from the distal end to the proximal end (over the entire area in the vertical direction). Water can be discharged to the outside of the box body through the round hole 7.

Furthermore, a guide groove 16 for receiving water discharged from the notches 19, 19 is carved on the upper end surface of the antenna holding part 11, along the outer periphery of the base end of the mounting part 13. Further, the flange 12 has a larger diameter than the round hole 7, and drain grooves 17, 17 extending radially outward from the guide groove 16 are recessed in the upper surface of the flange 12.
