In this case, the gap formed between the eaves ridge 4 and the eaves tip 2 becomes large, and the appearance is poor. Further, in FIG. 6, a gap is formed between the locking projection 20 and the downward projection 43 of the eaves rod suspension 3 so that the rear ear portion 26 of the eaves rod 4 can pass. There is a possibility that the ear portion 26 passes through this gap and falls off.

  Further, for example, Patent Document 1 discloses a support structure shown in FIG. The eaves hook 3 in this support structure projects the mounting portion 8 downward from the rear end of the support portion 14. A locking projection 20 protrudes backward from a position facing the mounting portion 8 of the support portion 14, and an ear storage space 21 that opens backward is mounted above the locking projection 20. It is formed to face the portion 8. The rear ear portion 26 of the eaves basket 4 is housed in the ear portion housing space 21 and is locked to the upper surface of the locking protrusion 20 as in FIG. In addition, an ear detachment preventing member 29 held by the eaves rod suspension 3 is disposed in a gap formed between the rear wall portion 4c of the eaves rod 4 and the attachment portion 8 of the eaves rod suspension 3 facing the same portion. is doing.

However, in the support structure disclosed in the above-mentioned Patent Document 1, since the attachment portion 8 of the eaves hook suspension 3 is interposed between the ear detachment preventing member 29 and the eaves edge surface 2, the eave ridge 4 is increased by this amount. It is located away from the surface 2 on the outdoor side and has a poor appearance.
