PROBLEM TO BE SOLVED: To eliminate the insulating film removal work for a member before housing assembly work and wire continuity work for a housing member by forming a protrusion at a fitting part, and peeling off the insulating film of a fitting mate with the protrusion for electric continuity. SOLUTION: A protruding part 17 for fitting is formed at one metallic part (protruding side) 23 to be jointed, and a recess 18 for fitting is formed at the other metallic parts (recess side) 24, 25. The protrusion 17 has an insulating film 19 such as coating or plating having insulation properties to prevent the metallic part from being corroded. A protrusion 20 is formed at a fitting part for electric continuity between the metallic parts. The protrusion 20 has a size large enough to form electric continuity between the metallic parts, and the insulating film 19 is peeled off by insertion force for fitting the part for electric continuity. It is thus possible to eliminate the insulating film removal work for a member before assembly work for a housing body such as a distribution panel and work for bringing respective housing members in continuity with an electric wire or the like. It is also possible to carry to coating for each part and facilitate automation.
