Abstract

PROBLEM TO BE SOLVED: To eliminate water leak into a cabin by bringing the upper surface of the vehicle outside of the hollow seal part of the upper part of a run-channel into elastic contact with the lower end of the vehicle outside of a sub-seal and providing a slit having narrow possible width in the front and rear direction of a place pressed by the tip of a vis at the center of the upper surface of the hollow seal part. SOLUTION: A hollow seal part 4b receives the upper end of a raised door glass 7 in the state of elastic contact to seal a part between the inside and the outside of a cabin and is integratedly connected to the surface of the outside of the vehicle of the upper end part of a roof-side base bottom part 4a. A seal lip 4c is projected into the lower end of the surface of the vehicle outside of the roof-side base bottom part 4a and is brought into elastic contact with the inner surface of a door glass 7. Also, a slit 4e having narrow possible width put in the center of the upper surface of the hollow seal part 4b is provided in the front and rear direction of a place pressed by the tip of a vis, and it is preferable that the width is approximately 1mm. Thus, since the width of the slit 4e is reduced, the rigidity of the hollow seal part 4b is increased and the pressing force of the lower surface of the sub-seal 5 of the outside part of the vehicle is increased, so that a water leak quantity from a boundary face is greatly reduced.
