Abstract

<P>PROBLEM TO BE SOLVED: To provide a waterproof member of a wall surface piercing pipe capable of holding the waterproof function over a long period of time and facilitating the construction. <P>SOLUTION: The waterproof member 10 comprises a cylinder part 10A for inserting the wall surface piercing pipe 30 piercing through the wall surface and a flange part 10B formed in the outer periphery of the cylinder part 10A to abut on the wall surface. Protrusions 12 abutting on the whole outer surface of the wall piercing pipe are formed on the inner surface of the cylinder part 10A. As water is spurned by the protrusions for waterproofing, the aged deterioration can be prevented by the waterproof member better than by a wet seal material, and therefore, the waterproof function is held over a long period of time. <P>COPYRIGHT: (C)2003,JPO
