Title:
SLEEVE FOR PIPING AND WIRING, AND WALL PENETRATION PART STRUCTURE USING THE SLEEVE
Document Type and Number:
Japanese Patent JP2014141996
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To improve design performance by avoiding the exposure of a screw of a cap screwed to a cylinder part while imparting a waterproof gradient being an ascending gradient toward indoors from outdoors to an internal face of the cylinder part which is arranged in a wall penetration part, in a sleeve for piping and wiring, and a wall penetration part structure using the sleeve.SOLUTION: In a sleeve 10 for piping and wiring, a face opposite to walls W of flanges 12A, 12B is orthogonal to an axial core c of a cylinder part 11, and an upper thickness t1 of one flange 12A is made thicker than a lower thickness t2. An upper thickness u1 of the other flange 12B is made thinner than a lower thickness u2. Screw grooves ea, eb for screwing caps 20A, 20B to the direction of the axial core (c) of the cylinder part 11 are formed at both end internal faces of the cylinder part 11.
