なつている。(Embodiment) An embodiment of the present invention will be described below with reference to the drawings. As shown in FIG. By bending at the connecting part 3,
From the open state shown in FIG. 1 to the open state shown in FIG. 8, they are superimposed on each other as shown in FIG. Main case 1
A notch recess 4a is formed in a part of the rear end side of the peripheral wall 4, and a spring 5 is integrally molded with resin via a bendable connecting part 6 to the main body case 1, continuous with the notch recess 4a. There is. The spring 5 includes a base 7 continuous to the connecting part 6, an elastic part 8 bent in a meandering manner from the base 7, a blade coupling part 9 formed at the tip of the elastic part 8, and an operation on the opposite side. It consists of part 10. At the beginning of molding, this spring 5 is located outside the main body case 1 as shown in FIG. The springs 5 are stacked one on top of the other, and the spring 5 is housed in the main body case 1, and the protruding wall 7a formed on the base 7 is continuous with the peripheral wall 4 and closes the notched recess 4a.

A plate spring portion 15 having a locking protrusion 15a is formed on the front side of the guide hole 14. When the operating portion 10 is positioned at the rear end of the guide hole 14 under the bias of the elastic portion 8 of the spring 5, the blade body 13 is accommodated in both cases 1 and 2. Then, when the operating section 10 is pushed forward against the bias of the elastic section 8, the blade 13 is pushed out from the opening 11a formed at the front end of the guide passage 11 when the cases 1 and 2 are overlapped, as shown in FIG. Both cases 1 and 2
projected outwards. In this state, the operating portion 10 is located at the front end of the guide hole 14 and is locked by the locking protrusion 15a of the leaf spring portion 15, so that the protruding position of the blade 13 is maintained. On the other hand, when the operating section 10 is pushed backward to release the engagement between the operating section 10 and the locking protrusion 15a of the leaf spring section 15, the blade 13 is housed in both cases 1 and 2 again by the return of the elastic section 8. Ru.
