As shown in FIGS. 3A (front view) and B (side view), the slider connection portion S has a substantially rectangular shape when viewed from the front, but has a rounded tip portion S10 and a root portion S30. Bulging left and right. Seen from the side, the tip S10 is thin, and the center S20 and the root S30 are about three times as thick as the tip S10.

The distal end portion S10 is provided with a through hole S11 for connecting a slider, which penetrates in the thickness direction. The central portion S20 is provided with a through hole S21 for connecting the slider connection portion S and the pull connection portion H, which crosses the thickness direction perpendicularly. The root portion S30 is provided with an insertion hole S31 which is open at the lower end and is integrated with the through hole S21. However, unlike the through hole S21, it does not open left and right. The upper end of the bulge portion S32 at the base is a shoulder portion S33 that slightly descends outward. Each of the elements S10, S20, S30 is integrally formed by metal working or plastic molding.

FIG. 4A (front view), FIG.
As shown in (side view), when viewed from the front, the upper 2/3
There are two projections H10 such as crab claws, and a rectangular mounting base H20 that supports these projections is provided below.
From the side view, it can be seen that the mounting base H20 is slightly thicker than the projection H10. Both elements H10,
H20 is integrally molded with plastic.

The projecting portion H10 has a bulging portion H11 in which the upper half is swollen left and right, and the connecting portion H1 having a thinner lower portion.
It is 2. The bulging portion has a shape such that the blade of the kitchen knife stands up to the outside, the tip H13 is slightly rounded and sharp, and the lower end is slightly upward with respect to the connecting portion H12. It has a portion H14.

The projection support H10 is provided with a through hole H21 for attaching the puller body, which penetrates in the thickness direction.

To assemble the slider connection S and the pull connection H, as shown in FIG. 2, the protrusion H13 of the pull connection is simply inserted into the through holes S31 and S21 of the slider connection.
