To provide a wall penetrating structure that can surely secure a water shut-off property without using a sealing material or the like, can maintain the water shut-off property even if irregularities exist on the internal face of a penetration hole, and hardly causes the displacement of piping and a penetration member while being penetrated with the piping.
A wall penetration member 7 is arranged at the penetration hole 5. The wall penetration member 7 is composed of a body 9, a water shut-off part 11 or the like. The body 9 is located in a region in which the piping 6 penetrates, and is a cylindrical member corresponding to the piping 6. The water shut-off part 11 is arranged at the external periphery side of the body 9 over the circumferential direction. The water shut-off part 11 is composed of an elastic member 13 and a water-expansible non-fabric 15. The elastic member 13 is formed astride a clearance between the external periphery of the body 9 and the internal periphery of the penetration hole 5. Similarly, the water-expansible non-fabric 15 is arranged inside the elastic member 13 astride a clearance between the body 9 and the internal periphery of the penetration hole 5.
