PROBLEM TO BE SOLVED: To provide a device housing body which improves the working efficiency during the installation.SOLUTION: A pull-in part 48, into which a cable Q may be inserted, is formed on a peripheral wall of a cover body 42. The peripheral wall of the cover body 42, which excludes the pull-in part 48, is formed as a double wall structure having a hollow part 45. The hollow part 45 is filled with a filler J having fluidity. In the structure, the filler J is not exposed to the front surface side of the cover body 42, and thus the filler J does not adhere to hands of workers and a construction during the installation and storage operation of a switch S. Therefore, the work efficiency of filling operation of the filler J is improved. |
