Preferred embodiments of the present invention are shown below. The vertical, horizontal, and front-rear directions in the present specification refer to the directions shown in FIG. 1, and in the present embodiment, one door is the left door 2a and the other door is the right door 2b. In FIG. 1, 1 is a housing main body, and 2 is a double door having a double door composed of a left door 2a and a right door 2b. Both doors 2 are closed by overlapping the left end of the right door 2b, which is closed later, with respect to the right end of the left door 2a, which is closed first by the rotation axis in the vertical direction. As in the conventional case, a draining portion 3 as shown in FIG. 2 is formed on the peripheral edge of the opening of the housing body 1. The draining portion 3 is provided with a left packing 4a provided in a substantially U shape on the inner peripheral edge portion of the left door 2a and a substantially square shape provided on the inner peripheral edge portion of the right door 2b as shown in FIG. The right packing 4b comes into contact with each other to prevent water from entering the housing body 1. Further, as shown in FIG. 1, the left door 2a is provided with a handle 5 for moving a lock bar (not shown) locked on the back surface of the draining portion 3, and the right door 2b is formed on the left door 2a. A clamp-type handle 6 for sandwiching a locking piece (not shown) is provided. Then, both doors 2 are locked in the closed state by operating both handles 5 and 6.

As shown in FIG. 4, at the right end of the left door 2a, a recess 7 having a substantially U-shaped horizontal cross section extending in the vertical direction of the housing and recessing in the depth direction (rear) of the housing is formed. Drainage metal fittings 10 formed in a substantially U-shaped vertical cross section are welded to the upper and lower ends of the recessed portion 7. By providing such a recessed portion 7 and a draining metal fitting 10, even if water infiltrates from above the mating portion where both doors 2 overlap, water droplets will be discharged in the order of the upper draining metal fitting 10, the recessed portion 7, and the lower draining metal fitting 10. It is supposed to be transmitted and prevent water from entering the housing body 1.

Further, as shown in FIG. 5, the draining metal fitting 10 provided at the upper portion includes a horizontal piece 11, a vertical piece 12 extending vertically downward from the front end portion of the horizontal piece 11, and a lower piece 13 welded to the recessed portion 7. It is composed of and. The lower piece 13 is formed so as to be inclined to the rear of the housing according to the shape of the recessed portion 7.

Here, as shown in FIGS. 5 and 6, the left packing 4a provided on the inner peripheral edge of the left door 2a is projected from the vertical piece 12 of the draining metal fitting 10 toward the right, that is, toward the right door 2b. It is assumed to have a protruding portion 20. The surface of the protruding portion 20 on the door side is inclined toward the inside of the housing toward the tip, and in the present embodiment, it is substantially the same as the gap 40 described with reference to FIG. 9 as a conventional problem. The shape, that is, the horizontal cross section is formed to be substantially triangular. By forming such a protruding portion 20 on the left packing 4a, the gap 40 generated by the conventional draining metal fitting 10 coming into contact with the right packing 4b provided on the right door 2b is completely eliminated as shown in FIG. It is possible to reliably prevent water from entering the housing body 1 from the mating portion of both doors 2.

In the present embodiment, the shape of the protruding portion 20 is substantially triangular in horizontal cross section, but the present invention is not limited to this, and when both doors 2 are closed, the draining metal fitting 10 is provided on the right door 2b. Any shape may be used as long as it can fill the gap 40 generated by the contact with the packing 4b.

Further, as shown in FIGS. 5 and 6, the protruding portion 20 is formed so as to be curved toward the housing body 1. Since the packing 4 is often attached to both doors 2 by human hands, the attachment position may vary. Therefore, by slightly bending the protruding portion 20 toward the housing body 1 as in the present embodiment, the protruding portion 20 is surely brought into close contact with the draining portion 3 of the housing body 1 when the left door 2a is closed. Therefore, it is possible to reduce the influence of the variation in the sticking position of the packing 4 described above. By slightly bending the protruding portion 20, when the door is opened, the vertical piece 12 of the draining metal fitting 10 and the standing side 20a of the protruding portion 20 on the draining metal fitting 10 side are as shown in FIG. A gap is created, but when the door is closed, the protrusion 20 abuts on the drainer 3 and is urged forward to eliminate the gap, and as shown in FIG. 7, the standing side is at the end of the vertical piece 12. Since 20a is in close contact with each other, it is possible to prevent water from entering. At this time, by making the length of the vertical side 20a in the depth direction substantially the same as the thickness of the vertical piece 12, the two can be brought into close contact with each other and water can be prevented from entering more reliably.

As shown in FIG. 8, the right packing 4b provided on the right door 2b has an expansion portion 30 whose end is expanded upward, and the expansion portion 30 is a vertical piece formed on the draining metal fitting 10. It is preferable to cover the upper part of 12. As a result, the expansion portion 300 covers the upper part of the gap 40, so that the waterproof performance can be further improved, and water can be more reliably prevented from entering the housing body 1 from the mating portion of both doors 2. It is supposed to be possible.
