The guide rail 18 is attached to the upper surface of the protruding portion 11, and a mounting bolt 20 is provided below from a location corresponding to the recess 16 in the bottom wall of the guide rail 18, and the mounting bolt 20 is inserted into the mounting hole 17. The guide rail body 3 is fixed to the roof 1 by fastening a nut 21 to the lower end of the mounting bolt 20. A weather strip 22 is mounted inside the guide rail 18. 23 is a packing, which is fitted onto the mounting bolt 20 and inserted into the recess 16.
It is interposed between the bottom wall and the guide rail 18 inside. The outer end of the curved portion 19 is in contact with the upper surface of the roof 1 via the intervening body 24.

The roof 4 has a hollow double structure, and a reinforcing rib 25 is integrally formed on the bottom wall of the roof 4, and a lining material 2
6 is fixedly installed. All around the four ends of the roof,
An outwardly projecting slide edge 27 is formed, and the edge 27 is provided within the weather strip 22 of the guide rail 18 so as to be slidable in the front-rear direction.

According to the embodiment configured as described above, a part of the rainwater etc. that flows down the top surface of the roof 4 passes through the inside of the guide rail 18 and is discharged from the rear end.
Also, the water overflowing from the guide rail 18 is drained to the rain gutter 12.
The water that has entered the rain gutter 12 flows out from the labyrinth channel 15 to the outer side of the protrusion 11.

In this case, the guide rail 18 is attached to the upper surface of the protruding part 11 that protrudes upward from the roof 1, and the overlapping surface of the protruding part 11 and the guide rail 18 is located above the bottom wall of the rain gutter 12.
