The combination of the concave and convex fitting portions is shown in FIG.
As shown in the figure, the upstream side of the band D insertion (arrow direction) is convex.
Downstream is the combination that is concave shaped portion o at the shaped portion t. This is a form adopted as a result of testing a combination of concave and convex fittings.
It has been found that most of the cases where are caught by the concave and convex fitting portions are portions where gaps are formed on both sides. For this reason, books
In the invention, a concave-shaped portion o the side disposed downstream to form the rounded portion r to both ends of the concave shaped portion o a gap on both sides is produced. Therefore, the band D at a portion where a gap is formed the both sides is a stable posture by being guided by the convex portion t continuous from the upstream side, yet both sides in the round portion r of the concave shaped portion o of the moiety Can be passed smoothly because the is formed. The cause I combination of convex-concave engagement is higher than some upper surface of the concave shaped portion o the upper surface of the convex portion t as shown in FIG.

On the other hand, as shown in FIG. 6, a concave portion o is disposed on the upstream side of the band D insertion, and a convex portion t is disposed on the downstream side of the band D.
Further, a shape in which a round portion r is formed on both sides on the concave portion o side and both sides on the convex portion t side is also conceivable. In this case, it is conceivable that the attitude becomes slightly unstable immediately after the tip of the band D passes over the convex part t when passing through both sides of the convex part t. Therefore, the structure shown in FIG. preferable.
