Japanese Patent JP2012107749

Kind Code:

A

Abstract:

To provide a wall penetration device stably fitting an elastic sealing material in a wall hole uniformly on the whole periphery.

The wall penetration device includes: an edge member 21 arranged at the front opening of a wall body W penetrating through the wall hole H; a cylindrical member 10 arranged inside of the wall hole H; and an elastic seal member 11 interposed between the cylindrical member 10 and the wall body W and having a water stopping function in a uniform compression state. A back member 24 engaged with and abutting on the back of the wall body W is provided as a connection means for integrally fixing the edge member 20 and cylindrical member 10 to the wall body W. The cylindrical member 10 is formed separately from the edge member 20 by a circular diameter-enlarging body enlarging a diameter to the inner peripheral surface of the wall hole H, and is configured by affixing the elastic seal member 11 to the whole periphery. Thereby, stable water stopping over the whole periphery is secured between the wall hole H and the cylindrical member 10 by a simple fitting operation.
