ものとなる。 An oblong upper piece 2 and a lower piece 3 across the base pivot 1.
can be folded and expanded freely. In order to provide rigidity, the upper piece 2 and the lower piece 3 are provided with concave ribs 2a and 3a of the same shape in the middle part except for the periphery, and the concave rib 2a of the upper piece 2 is located earlier than the concave rib 3a of the lower piece 3. Only the front side is made shorter. 4 is a fitting hole provided in the middle of the tip side of the lower piece 3, and the fitting hole 4 is connected to the peripheral edge and the concave rib 2.
a, and is parallel to the pivot 1 on the tip side that is stepped with respect to the recessed rib 3a of the lower piece 3, and is hooked to and detached from an elastic hook to be described later. 5 and side edges 6a, 6b orthogonal to the stepped height latching edge 5 are provided on both sides of the recessed rib 2a. The upper piece 2 is attached to the lower piece 3 at a position facing the fitting hole 4 by folding it up after cutting the die.
latching pawl 7 and side edge 6a, which are hooked on and removed from the stepped latching edge 5;
Steady rest pieces 8a, 8b for steady rests are formed to fit inside the respective side edges 6a, 6b at a height of 6b. In addition, the latching claw 7 has sufficient elasticity for latching because it has a distance to reach the step height latching edge 5, and the steady rest pieces 8a and 8b have a short distance that is the same height as the side edges 6a and 6b. The rigidity is stronger than that of the latching claw 7.

嵌合することとなる。 When folding the bi-folding fitting of the present invention, the upper piece 2 is rotated and stacked on the lower piece 3 based on the pivot 1, and in the process, the stepped latching edge 5 is hooked to the latching claw 7. Also, the side edges 6a, 6b fit on the outside of the steady rest pieces 8a, 8b.

率を向上することができるという効果を生ずる。<Effects of the invention> As described above, in the present invention, steady rest pieces are provided on both sides of the latch claw so that they fit with the side edges of the fitting hole when the upper piece is folded, so that the gap between the upper and lower pieces is reduced. This has the effect of reliably preventing lateral wobbling. In addition, the latching claw and the latching edge that engages and disengages are stepped up to increase the distance between the latching claws, which gives the latching claw sufficient elasticity for engaging and disengaging, and prevents side-to-side vibration. By making the distance of the stopper piece as short as possible, it is possible to maintain rigidity and prevent bending and deformation during use as much as possible. Furthermore, since the latch claw and steady rest piece are simultaneously formed in one die-cutting process, the number of processes can be reduced and manufacturing efficiency can be improved.
