Even when the eaves rod 18 protrudes outward from the nose cover plate disposed at the eaves edge, a reliable fitting can be achieved. For this reason, the construction efficiency which connects the edge parts of the eaves rod 18 orthogonally arranged in the protrusion corner part of an eaves tip at right angle improves further.

  Moreover, since the return piece 17 that protrudes outward from the eaves outer bending joint 1 is disposed at the side edge of the guide piece 15 on the fitting portion 3 side, the eaves outer bending joint 1 is provided by the guide piece 15. The end portion of the rear wall portion 18a of the eaves rod 18 drawn to the side can be pressed against the rear wall portion 3c side of the fitting portion 3 by the return piece 17, and provided at the upper end of the front wall portion 18c of the eaves rod 18. When the front ear portion 21 is fitted into the front ear portion 7 of the front wall portion 3a of the fitting portion 3, the end portion of the rear wall portion 18a of the eaves rod 18 is prevented from coming off so as to escape from the guide piece 15, The fitting portion 3 of the outer bending joint 1 can be reliably fitted to the inside of the end portion of the eaves rod 18. Connection work can be performed smoothly.

  Even if the allowance from the outer surface of the rear wall part 3c of the fitting part 3 of the guide piece 15 including the return piece 17 in the eaves eaves bending joint 1 is sufficiently small, the end of the rear wall part 18a of the eaves eaves 18 is The eaves hook can be reliably pulled into the bent joint 1 side, and escape from the guide piece 15 at the end of the rear wall portion 18a of the eaves hook 18 can be prevented. The guide piece 15 and the return piece 17 do not interfere with the eaves and do not obstruct the connection work of the eaves rod 18.

  Thus, the outer peripheral surface of the joint body 2 of the eaves outer bending joint 1 in which the ends of the eaves eaves 18 arranged orthogonally at the protruding corners of the eaves are connected at right angles, that is, the front wall portion 2a and the bottom wall portion. The outer peripheral surface 5 formed from the outer surfaces of 2b and the rear wall portion 2c is more than the outer peripheral surface 5 of the joint body 2 by the step 6 having a dimension slightly larger than the thickness or the thickness of the outer peripheral wall portion of the eaves bowl 18 as described above. Since the outer peripheral surface 4 of the fitting portion 3 is disposed on the inner side, the outer peripheral surface of the eaves rod 18 is disposed substantially flush with the outer peripheral surface of the eaves rod 18, and the joint portion between the eaves outer bending joint 1 and the eaves rod 18 is inconspicuous. The fact that 18 is connected by the eaves-bend bend joint 1 is hardly visible in appearance, and a sense of unity appears as if the eaves are bent at a right angle.

  Moreover, the connection strength is increased by using the adhesive together, and even if surplus adhesive is generated, the surplus adhesive is received by the adhesive escape groove 13 and does not leak to the joint body 2 side. A good finished appearance can be obtained.

  In addition, the eaves outer bend joint of the present invention can be integrally formed, for example, by extruding synthetic resin or cutting and bending a composite material in which a thin metal plate is insert-molded in the synthetic resin. .
