No. 04384, Japanese Utility Model Application Laid-Open No. 62-79080 and the like. These braids are basically provided with cutouts which are fitted to each other in a state where they are crossed on one of the braids and the other braid. As means for maintaining the fitted state, the former actual opening 57-204 is used.
In the kumiko described in Japanese Patent Publication No. 384/384, a wedge portion swelling in the width direction is formed on at least one upper side of the knitting beam, and the wedge part described in the latter Japanese Utility Model Publication No. 62-79080 is used. In the child, a protrusion is formed near one end in the height direction facing the notch on one side portion in the width direction of one of the pair of crosspieces and is engaged with the back surface of the other pair of crosspieces.

[0003]

However, in the former braid, the fitting state of the braided crosspieces is maintained by utilizing the frictional resistance of the wedge portion. Not only is it difficult to perform the assembly (the set beams are easily detached from each other), but also the fitting must be performed by press-fitting, so that special equipment is required for assembling, and there is a drawback that labor and manufacturing costs are increased. Further, in the latter knit, since the projection of one of the knots is engaged with the back surface of the other knot, the mating state of the knots is maintained.
Although it is easy to maintain the fitted state, special processing is required to form the projections, and thus there is a disadvantage that the cost must be increased.

Rib-shaped protrusions 6 and 7 in the center along the longitudinal direction
It is molded into a continuous long shape having The cutouts 4 and 5 are cut to a substantially central portion in the height direction, and preferably to a central portion in the height direction, with a diameter substantially equal to the width of the knot bars 1 and 2. That is, the notch portion 4 is provided on one of the knitting bars 1 from the upper surface thereof downward to the center in the height direction, and the other knitting member 2 is provided with the notch portion 4 extending upward from the lower surface thereof at the center in the height direction. It is preferable that the notch 5 is provided up to the portion. It should be noted that the braid 3 in the present embodiment is constructed so as to be assembled not in a cross shape in which the braid bars 1 and 2 cross at a right angle, but in a so-called hycyclos shape in which the crosses intersect at an acute angle or an obtuse angle.

The protruding portions 6 and 7 are notch portions 4 and 7 respectively.
5 has an inclined surface (oblique side) 8 that gradually expands in the depth direction (fitting direction) and a bottom surface (bottom side) 9 orthogonal to the depth direction.
, And preferably a right-angled triangle. In this case, the bottom surface 9 of the triangular cross section is substantially at the same position as the bottom of the cutouts 4, 5 so that the protrusions 6, 7 are cut along the same cut plane as the cutouts 4, 5, preferably the cutouts 4, 5. 5 is set at the same position as the bottom surface, that is, at the center in the height direction of the pair of bars 1 and 2.

When assembling the gang 3 with the gang bars 1 and 2 configured as described above, first, the gang bars 1 and 2 are crossed so that the cutout portions 4 and 5 face each other. What is necessary is just to press and fit both the sets 1 and 2 from the height direction. At the time of this fitting, as shown in FIG.
