Abstract: PURPOSE:To prevent a sunroof from rusting by providing the outer wall of a gutter disposed on a sunroof frame with a water discharge tube connected to the inside of the gutter, connecting a connection tube surrounding the water discharge tube to the frame, attaching a seal member between the connection tube and the drain tube, and connecting a drain tube to the connection tube. CONSTITUTION:Rain or other water entering through the gap between the circumference of a window 3 and a sunroof panel 6 is received with a gutter 13 made of rubber or plastic and flows through a water drain passage 21 to a drain tube 29. Even if a reverse flow occurs in the drain tube 29, water is prevented with a seal member 22 from entering the connection tube 20 and further from entering a sunroof frame 4. As the drain tube 29 is connected to the connection tube 20 surrounding the drain passage 21, the drain tube 29 may be made with a material of a thick diameter having less low resistance. As the drain passage 21 has nothing to do with the connection of the drain tube 29, the passage as well as the gutter 13 may be formed with a soft material such as rubber.
