Sealing structure of motor vehicle
First Claim
1. A sealing structure for sealing around a door opening of a vehicle against a periphery of a vehicle door, comprising:
- a door opening portion formed around the door opening in a vehicle body, which is closed and opened by the vehicle door, said door opening portion being composed of an outer body panel and an inner body panel, an end edge of said outer body panel being placed on and joined to an end edge of said inner body panel with said outer body panel located on the side of said door opening, thereby forming a flat joint, said outer body panel having a concave surface which is composed of a first surface and a second surface, said first surface bending from said outside of said flat joint into an L-shaped configuration and extending outwardly of said door opening portion, and said second surface bending from said first surface into an L-shaped configuration and extending towards said side surface of said vehicle body; and
a weather strip having a base portion which is secured to said outer body panel of said door opening portion of said vehicle body, and a tubular seal portion which is pushed by the periphery of the vehicle door when said door opening is closed, said base portion having an L-shaped cross-section which conforms to said flat joint and said first surface of said concave surface, and being composed of an inner part which faces said flat joint, and an outer part which faces said first surface of said concave surface of said outer body panel, a seal wall which expands from said outer part of said base portion and fills a space defined by said concave surface, thereby sealing between said door opening portion of said vehicle body and the periphery of said vehicle door with said weather strip secured to said door opening portion.

Abstract
A sealing structure includes a door opening portion formed around a door opening in a vehicle body, and a weather strip secured to the door opening portion. The weather strip has a base portion and a tubular seal portion which is pushed by a vehicle door when the door opening is closed. End edges of an outer body panel and an inner body panel which compose the door opening portion are placed on and joined to each other, thereby forming a flat joint. The outer body panel has a concave surface from the outside of the flat joint to a side surface of the vehicle body. The concave surface is composed of a first surface which bends from the outside of the flat joint into an L-shaped configuration and extends outwardly of the door opening portion, and a second surface which bends from the first surface into an L-shaped configuration and extends towards the side surface of the vehicle body. The base portion of the weather strip has an L-shaped cross-section in conformity with the flat joint and the first surface, and the tubular seal portion of the weather strip has an arc-shaped seal wall expanding from a part of the base portion, which faces the first surface, and fills a space defined by the concave surface.
