Abstract: There is provided a weather strip for use on a sunroof capable of preventing squeak noises being generated in advance between a hollow seal part and a roof panel during traveling of a car by allowing the hollow seal part to satisfactorily follow vibrations of the roof panel. The weather strip ensures sealing property between a roof glass mounted on the sunroof of a car and a roof panel and comprises a built-in base part attached to the roof glass, and a hollow seal part composed of continuous ends integrally formed with the built-in base part and having substantially a circular cross section, a tip end contact part elastically contacting the roof panel, wherein thicker parts protruding inward and being continuous with the built-in base part are formed on the continuous ends of the hollow seal part and protrusions protruding inward are formed on substantially middle parts between the continuous ends and the tip end contact part.

Abstract: In an automotive sun roof system, each of the front sliders is provided with at least three laterally extending slide shoes including a front inboard slide shoe, a rear inboard slide shoe and a front outboard slide shoe located intermediate between the inboard slide shoes with respect to a fore-and-aft direction, and the guide rail is provided with an inboard side defining an inboard guide slot and an outboard side defining an outboard guide slot adapted to receive the corresponding slide shoes, the outboard side of the guide rail being provided with a front end which is rearwardly offset from that of the inboard side of the guide rail. Thus, the front end of each guide rail is advanced as much as possible without increasing the exposure of such parts to the moisture that may drip from the fixed roof panel and/or moveable panel by taking into account the rounded shape of the opening in the fixed roof panel.
