Abstract

A sealing structure for use on an automobile having a weather strip and an interior member wherein the weather strip includes an installation base member having an inner-cabin side wall, an outer-cabin side wall, a connecting wall and holding lips; and a seal member. The installation base member couples to a flange vertically formed along a peripheral edge of an opening corresponding to a door. The seal member is formed on the outer-cabin side wall and makes elastic contact with a door glass. The interior member is provided on an inner-cabin side of the inner-cabin side wall. An end of the interior member extends toward the connecting wall. A projection is formed on an outer circumference of a connecting part between the outer-cabin side wall and the connecting wall. The projection extends in an internal circumferential direction and covers the end of the interior member from an outer-cabin side.

Claims

1. A sealing structure for an automobile, the automobile being provided with a weather strip and an interior member, the weather strip comprising:

an installation base member configured to operably couple to a flange, the installation base member having a substantially U-shaped cross section including an inner-cabin side wall, an outer-cabin side wall and a connecting wall which connects the side walls and a plurality of holding lips formed on an inner side, the flange being vertically formed along a peripheral edge of an opening corresponding to a door in an internal circumferential direction; and

a seal member configured to make elastic contact with a door panel or a door glass, the seal member being formed on the outer-cabin side wall of the installation base member,

the interior member being provided on an inner-cabin side of the inner-cabin side wall of the installation base member of the weather strip, wherein

an end of said interior member extends toward the connecting wall of the installation base member of said weather strip, and

a projection is formed on an outer circumference of a connecting part between the outer-cabin side wall and the connecting wall of said installation base member, the projection extending in said internal circumferential direction and covering up the end of said interior member from an outer-cabin side, the projection being a lump, and width of the projection in an inner-cabin and an outer-cabin direction being not less than length of the projection.

2. The sealing structure for the automobile as claimed in claim 1, wherein said flange is vertically formed on a back door, and the seal member of said weather strip is configured to make elastic contact with said door glass, the back door having said door glass provided thereon and opening and closing, the door glass being independent from the back door and capable of opening and closing.

3. The sealing structure for the automobile as claimed in claim 2, wherein the end of said interior member is bent toward a lower side from an upper side.

4. The sealing structure for the automobile as claimed in claim 1, wherein said projection comprises sponge material and said installation base member comprises solid material.

5. The sealing structure for the automobile as claimed in claim 2, wherein said projection comprises sponge material and said installation base member comprises solid material.

6. The sealing structure for the automobile as claimed in claim 3, wherein said projection comprises sponge material and said installation base member comprises solid material.
