In this embodiment, when molding the fastener of the present invention, the base plate 1 and the restraint plate 2 are integrally molded, and at this time, the rotation shaft 8b is formed at the same time as the shaft hole 9 of the bearing portion 8a is formed.
This method is used to simplify the assembly of the two by molding them in a fitted state.

FIG. 5 shows an enlarged view of this hinge part 8. The thin piece 10 connecting the bearing part 8a and the rotation shaft 8b is formed by the flow of resin during molding, and the rotation of the restraining plate It is automatically cut by the

On the other hand, the locking part 7 is provided adjacent to the rising wall 3, and here, the locking part 7 is provided so as to face one rising wall 3.
1 is formed as a U-shaped groove that stands up and opens upward.

This locking part 7 has stoppers 12 in the form of non-return claws arranged in a staggered manner on the opposite surface of the opening, and a guide piece 11a with an inclined surface that opens outward is provided at the upper end of the wall 11. There is.

A locking pawl 13 extending perpendicularly to the locking portion 7 is provided at the free end of the restraining plate 2 .

This locking pawl 13 has hooking pawls 14 provided on both sides of the tip thereof so as to correspond to the staggered stoppers 12, and the locking pawl 13 is locked using the guide piece 11a as a guide. When pushed into the portion 7, this hook is hooked onto the stopper 12 to prevent it from being released.

The guide piece 11a not only functions as a guide during engagement, but also serves as a release piece that opens the opening of the engagement part 7 to disengage the stopper 12 when disengaging the engagement claw 13. There is.

In the figure, reference numeral 15 denotes a pillow part that is provided so as to protrude further upward from the upper end of the rising wall 3 standing in the middle, and when the restraining plate 2 is closed, this pillow part comes into contact with the middle of its length. The restraint plate is forcibly bent and tensed to prevent the restraint plate from wobbling during use.
