- a threading flange 122D is formed on the other end 122B.
- the sleeve 12 is inserted through the penetration hole 11 of the concrete wall 10 as the partition body, and one cable is attached to the sleeve 12 14 are passed through.
- the cover cap 120 is assembled to cover the gap between the one end 12A of the sleeve 12 and the cable 14. At this time, since the cover cap 120 is composed of the two parts 120A and 120B, the assembly is easy.
- one end 122 A of the casing 122 is attached to the outer peripheral surface 12 B of one end 12 A of the sleeve 12, and the other end 122 B is on the outer peripheral surface 14 A of the cable 14 or It is arranged near the surface 14A. That is, the bulging opening 122c is located on the outer peripheral surface 14A of the sheath 14 or in the vicinity of the outer peripheral surface 14A.
- An adhesive tape or an adhesive is preferably provided between the other end 122 B and the outer peripheral surface 14 A of the cable 14.

- the cable 14 is disposed so as to pass through the opening 126, and fixed by winding the pressing member 16 made of, for example, a wire or a band around the assembly flange 122D. it can.
- the filling material is formed in the space formed between one end 12A of the sleeve 12, the cover cap 120 and the cable 14 as in the test 3 of Example 1. It is possible to fill
- the heat expands the thermally expandable material 124 due to the heat.
- One end 122 A of the casing 122 is closed, so the thermal expansion is performed.
- the elastic member 124 also bulges only at the bulging opening 122C.
- the bulging opening 122c is located on the outer peripheral surface 14A of the cable 14 or in the vicinity of the outer peripheral surface 14A. Therefore, since the thermally expandable material of the increased volume bulges toward the cable 14, the gap can be closed earlier and more reliably even if the cable 14 is burnt out.
- cover cap 120 is also configured as a two-component force, assembly is possible and convenient even when the cape 14 is inserted.
