Abstract
Abstract An electrical junction box having a double-wall structure includes a container body and an upper cover to be mounted on the container body. A peripheral wall of the container body is composed of an outer wall and an inner wall. There is provided a horizontal rib between the outer wall and the inner wall for partitioning a space between the outer wall and the inner wall into an upper space and a lower space. A plurality of upper ribs and a plurality of lower ribs extending in a vertical direction are respectively provided at a determined interval above and below the horizontal rib. The horizontal rib is provided with communicating holes, between respective pairs of the upper ribs, which communicate the upper space with the lower space.
