<p>PROBLEM TO BE SOLVED: To provide a wall penetration member, wall penetration structure of pipe in which installation is easy and they have a high degree of freedom in installation, and a method for fixing penetration pipe to a wall.SOLUTION: A second flange part 3b is raised outward in substantial perpendicular to an axial direction of a pipe part 5. A connecting part 3c of a prescribed length bent forward at a base part of a second flange part 3b is formed along the pipe part 5. Near the front end of the connecting part 3c, the first flange part 3a is raised substantially in parallel with the second flange part 3b. The outer diameter of the first flange part 3a is larger than that of the second flange part 3b. Further, a location near the extremity end of the first flange part 3a is bent forward of the wall penetration member 1. At the rear surface of the first flange part 3a and at a location near the outer peripheral part is arranged a resilient member 7. The first flange part 3a and the second flange part 3b are arranged to be spaced apart only by a length of the connecting part 3c. The outer peripheral part of the connecting part 3c is provided with a water expansible member 15.</p> |
