Claims

[Scope of utility model registration request]

It consists of a mounting base that is fixed to the periphery of the door of the opening/closing part of an automobile, and a hollow seal part that comes into elastic contact with the side edge of the car body opening protruding from the mounting base. At both ends of an extrusion-molded weather strip made of a flexible material such as rubber, the weather strip has a cross-sectional shape that is elastically deformed by shrinking and expanding to improve the closing and sealing performance of the door. From a substantially flat molded mounting base that joins the mounting base and is fixed to the peripheral corner portion, and a molded hollow seal portion that connects and communicates with the joined end hollow seal portion protruding therefrom and comes into elastic contact with the side edge corner portion. The weatherstrip is formed by endlessly joining bent joint parts of the same type as the above by molding, and the seal part exhibits the same performance by the pressure acting in the molded hollow part of the weatherstrip. The corner joint structure is such that both joint ends of the bent joint have a cross section that is substantially the same as the outer shape of each surface to be joined, and are sequentially deformed toward the center of the corner, and the center thereof has an approximately semicylindrical hollow cross section. More specifically, both joint end portions have an outer wall section on the outside of the vehicle of the molded mounting base and an inner wall section on the inside of the vehicle that has a bending/stretching wall section at the upper end that can be bent/stretched by the pressure action. A molded hollow seal portion is formed by connecting a bulging seal wall portion between the wall end of the wall portion and the inner wall portion side, which is elastically deformed into an uneven shape due to the pressure action and comes into non-elastic and elastic contact with the side edge corner portion. In the central portion, inner and outer walls are provided on the outside of the car interior of the molded mounting base, and the upper ends of these walls are elastically deformed into uneven shapes by the pressure action, forming side edge corner portions. A corner joint structure of a weather strip characterized by having a cross-sectional configuration in which a molded hollow seal part is provided by connecting an upper wall part that makes non-elastic contact and an elastic contact part.
