However, since the lower surface of the gutter groove 9 is received by the gutter portion 13 of the connection frame 11, rainwater that has entered the gutter portion 13 can also flow down to the eaves. That is, the reliable waterproof function can be continuously exerted for a long period of time. There is a risk that the paragraph 7 and the engagement step 8 will corrode and rainwater will infiltrate into the seat wall 14 side.
It can prevent rainwater from entering the inner surface of the roof by catching rainwater and flowing it down to the eaves.

The clip 23 is preferably formed as a long material, but it may be formed in a short frame shape so as to engage and hold the adjacent gutter grooves 9 at regular intervals. The connection frame 11 and the clip 23 can be formed of an aluminum mold material or a plastic mold material. Fastening part 12
