PROBLEM TO BE SOLVED: To simplify the connection of a conductive tube to the shielding part of a housing. SOLUTION: The joint 26 of a housing 20 fitted to a shielding box 10 is inserted into the elastic joint 34 of a metallic foil tube 30. Since the elastic joint 34 has troughs 37 peaks 35 formed alternately continuously over the whole periphery and provided with ridgeline parts 36, 38 stretching along its axial line, and is formed into a tapered shape so that its inside diameter at parts approximately from the center to the rear part may be smaller than the outside diameter of the joint 26, the formation angles of the peaks 35 and troughs 37 are widened to gentle angles, and the diameter of the rear part of the elastic joint 34 is widened and displaced in the direction shown by arrow A, by insertion into the metallic foil tube 30. Consequently, an elastic force is generated in the direction of diametric shrinkage in the elastic joint 34 and held by joint 26 elastically, and it becomes possible to electrically connect the metallic tube 30 to the housing 20 easily. |
