PROBLEM TO BE SOLVED: To enhance waterproof sealing effect by reinforcing connection of waterproof object with a connector. SOLUTION: A fitting hole 111 and an exhaust outlet are provided on a bottom wall 110 of a box-shape outer shell member 100 penetrating it. At a bottom wall 210 of a box-shaped sealing member 200, a fitting protrusion 221 is provided protruding toward outside with its tip side thinner than the inside diameter of the fitting hole 111 and its root side thicker than the same and equipped with a through-hole at a center axis penetrating down to the bottom wall. Along an opening edge of the side wall 230 all along the circumference, a thick-wall part 230 thicker than other parts of walls. In containing the sealing member 200 inside the outer shell member 100, the outer periphery of the fitting protrusion 220 hits the edge of fitting hole 111 to stop, in which state, a connector 500 is gradually contained until it hits the bottom wall of the sealing member, with the inside air exhausted proportionately. When it is further pushed in, the sealing member 200 keeps on being contained as the inside air is exhausted until its bottom wall hits that of the outer shell member 100, the through-hole 221 finally filled up.
