It is set short. Since the protruding lengths of the trailing edge flange 3a and the side edge flange 3b are different as described above, the notch 4 is formed in the corner portion C of the peripheral edge flange 3 and the trailing edge flange 3a is formed with the notch 4 as a boundary.
And the side edge flange 3b are continuously formed. Reference numeral 5 is a rear reinforcement which is joined and arranged at the rear edge of the roof opening 2 over the rear edge flange 3a and its bent base. The terminals at both ends are joined to the roof side of the roof panel 1, and Curved corner portions 5a are formed on the both ends so as to surround the corner portion C of the peripheral flange 3 and are joined and arranged along the corner portion C. 6 is joined to the side edge of the roof opening 2 over the side edge flange 3b and its bent base,
With the side drain force arranged, a straight extending portion 6a is formed at a rear edge portion of the side drain force 6, and the extending portion 6a intersects both end portions of the rear reinforcement force 5. And is joined to the rear reinforcement 5, and the notch 4 is closed by the extending portion 6a.

Here, in this embodiment, when the bracket 9 at the lower edge of the side force 6 is bent and formed inward and the roof panel 1 is dropped onto the roof side rail 10 to be joined, the bracket 9 is attached to the roof side rail 10. Therefore, the size of the roof opening 2 in the vehicle width direction is enlarged, and accordingly, the guide rail 11 is arranged as close to the roof side rail 10 side as possible, so that the head of the occupant can be prevented. We are trying to expand the clearance. In addition, the guide rail 11
Has a mounting sheet portion 12 formed on its outer edge,
A rising wall 13 is formed stepwise following the mounting seat portion 12, the rising wall 13 is arranged outside the side drain force 6, and the mounting seat portion 12 is fixed to the lower surface of the bracket 9 with a screw 15.
