きくなってしまう。[Problems to be Solved by the Invention] Sports competitions have been increasing year by year, and sports competitions that require vigorous movement have been devised, and even in conventional sports competitions,
It is increasing in number that athletes, that is, athletes, make extremely violent movements or put their clothes on the clothes due to the challenge of recording. In the prior art, the tension applied to the clothing by such sports competition cannot be withstood and the stitch structure may be damaged. On the other hand, it is easily conceivable that the first seam is composed of five seams to improve the strength of the seam structure, but this increases the width of the seam structure.

なわれてしまい、逆にデザイン性が低下してしまう。On the other hand, in sports competitions, not only the athletes but also the spectators tend to enjoy themselves. One of the factors that entertain the audience is the design of the clothing worn by the athlete. Of course, this design occupies an important position for athletes as a means of appealing to the audience and as one of the elements to control themselves from a mental aspect. For this reason, a garment made by sewing a large number of cloths having different colors and shapes is desired. However, in the seam structure having the wide width as described above, only the seam structure is conspicuous and the aesthetic appearance is spoiled, and conversely the design is deteriorated.

As shown in FIG. 10, the number of stitches of the first stitch 102 through which the cloths 100 and 101 are inserted is as shown in FIG.
In the case of the stacking region R1 shown in (1), two lines are shown in FIG.
In the case of the stacking region R2 shown in (2), one line, and further,
In the case of the stacking region R3 shown in FIG. 10 (3), a zero seam, that is, a flat seam seam structure without seams for inserting the cloths 100 and 101 may be formed. Of course, each cloth 10 among the seams forming the first seam is
It is extremely rare that the number of stitches that pass through 0 and 101 decreases, but the tensile strength decreases, so
It is desirable to be able to deal with this. In particular, FIG. 10 (3)
When there is no seam for inserting each of the cloths 100 and 101 as shown in, there is a possibility that a gap may occur between the cloths 100 and 101 due to the movement of the athlete as described above.

れることを防止することができる。As described above, according to the present invention, two cloths to be sewn are sewn by chain stitch in a state where they are partially overlapped. The first seam is formed by five seams including at least one seam that extends in the sewing direction with a predetermined width in the stacking area of each cloth and inserts each cloth in its thickness direction. Composed. As described above, the five stitches forming the first stitch can be formed in parallel with each other at a constant interval, so that a aesthetically pleasing stitch can be formed. Therefore, it can be easily used to sew clothes and the like that require design. Also the first
The width of the seam formed by the seam is equal to the constant width that has been conventionally formed, and in the conventional case, the number of seams constituting the first seam was four, whereas it was 5 Even if the number of books is increased, the width of the seam is prevented from increasing, and therefore, when the garment is sewn, it is possible to prevent the seam from being conspicuous and spoiling the aesthetic appearance.

上することができる。Further, even if the density of the seams constituting the first seams becomes high and the stacking area becomes small, almost certainly,
One stitch penetrates each fabric. Therefore, even if the athlete moves and external force acts so as to separate the cloths from each other, no gap is generated between the cloths. The second stitch is an area on the upstream side in the descending direction of the needle of one of the cloths, and is formed by engaging with each stitch constituting the first stitch. The third stitch is a region on the downstream side of the other cloth in the descending direction of the needle,
It is formed so as to be engaged with each seam that constitutes the first seam. As a result, the first stitch and the second and third stitches are engaged with each other, the stitches can be expanded and contracted, and the stitches forming the first stitch can be attached to each other. Therefore, the external force given by the movement of the athlete can be
It is possible to prevent a large tensile force from being applied to one seam by being dispersed in each seam constituting the seam, and to improve the tensile strength.
