PURPOSE:To eliminate a direct flood to a frame and recessing a frame bottom wall, and to enable a rust formation to be prevented and a head clearance to be expanded by forming a drain groove with a drain groove member having a U-shaped cross section and composed of a different member from the frame. CONSTITUTION:A foot part 29 of a frame seal 28 blocking between a sun roof frame 4 and the back surface 25 of a roof 1 is extended along the inner side surface 34 of the outer peripheral wall 26 toward a bottom wall 23 of a frame 4, and a drain groove part 36 as a drain groove member is integrally formed having a U-shaped cross section in an extended part 35. Thus, the requirement to provide a drain groove by recessedly providing the wall 23 of the frame 4 is eliminated, and the wall 23 of the frame 4 can be flatly formed. And a water dropped in the groove 36 flows into a drain tube 47, therefore the water does not directly touch the frame 4. Consequently, a head clearance can be expanded, and a special water proof treatment is not required.
