PURPOSE:To make it possible to prevent a drip exactly and at a low cost without using packing for preventing so that rain water does not go in, by providing a groove in the direction making a right antle with the cover opening direction, on the outside circumferential surface of the base of the apparatus storing box body. CONSTITUTION:A groove 14 is formed in the direction making a right angle with the opening direction of the base 1 by providing collars 12, 13 on the outside surface which is close by the opening end 11 of the base 1 of the apparatus storing box body. Also, the inside circumferential surface 22 of the cover 2 is fitted into the opening end of the collars 12, 13, and also a water discharge port 23 is provided at the position where the lower end of the groove 14 is opposed to the cover 2. According to this constitution, even if rain water goes in from the space of the overlapping part of the base 1 and the cover 2, it is led by the groove 14 and is discharged to the outside from the water discharge port 23. In this way, a drip can be prevented exactly and at a low cost without using packing. |
