Waterproof structure provided on device
First Claim
1. A waterproof structure that is provided on a device, comprising:
- a waterproof member that is interposed between a first member and a second member and is put in close contact with the first member and the second member by elastic deformation, thereby effecting waterproofing, wherein the waterproof member is a pipe that is formed by extrusion-molding a material with elasticity and anti-permeation properties, terminal-end faces of the pipe are disposed to be opposed to each other with their centers being aligned, and the pipe is extended by pressure that acts when the first member and the second member are engaged or attached to each other, whereby the terminal-end faces of the pipe are brought into close contact with each other and waterproofing is effected.

Abstract
A waterproof structure that is provided on a device includes a waterproof member. A pipe with no flash of a parting line, which is formed by extrusion-molding an elastic material such as a rubber or a resin, is used as the waterproof member. The waterproof member is interposed at a coupling part between members that is to be waterproofed, such that terminal-end faces of the pipe are disposed to be opposed to each other with their center (axes) being aligned (coaxial). When pressure is applied by engagement between the to-be-waterproofed members, the terminal-end faces of the pipe are put in close contact with each other. Alternatively, terminal-end portions of the pipe are juxtaposed with their centers being made parallel, and when pressure is applied, side faces of the terminal-end portions are put in close contact with each other. Thus, waterproofing is effected.

4. A waterproof structure that is provided on a device, comprising:
-
a waterproof member that is interposed between a first member and a second member and is put in close contact with the first member and the second member by elastic deformation, thereby effecting waterproofing, wherein the waterproof member is a pipe that is formed by extrusion-molding a material with elasticity and anti-permeation properties, terminal-end portions of the pipe are disposed to be adjacent to each other with their centers being made parallel, and an outer periphery of the pipe is collapsed by pressure that acts when the first member and the second member are engaged or attached to each other, whereby the side faces of the terminal-end portions of the pipe are brought into close contact with each other and the pipe is brought into close contact with the first member and the second member, thus effecting waterproofing.

6. A waterproof structure that is provided on a device, comprising:
-
a waterproof member that is interposed between a first member and a second member and is put in close contact with the first member and the second member by elastic deformation, thereby effecting waterproofing, wherein the waterproof member is a pipe that is formed by extrusion-molding a material with elasticity and anti-permeation properties, and has terminal-end faces at both ends, the first member is formed as an outer L-rib having a close-contact face at a wall face thereof, and the second member is formed as an inner L-rib that is engaged with the outer L-rib, and the pipe is fitted on an inner wall face of the outer L-rib such that the terminal-end faces of the pipe are opposed to each other at a distance with their centers being aligned, and the pipe is extended along the inner wall face of the outer L-rib when an outer peripheral surface of the pipe is pressed by engagement between the first member and the second member, whereby the terminal-end faces of the pipe are brought into close contact with each other.
