The inner end portion 51 of the first lateral direction D1 extends so as to intersect the first lateral direction D1 in the vertical direction D3.

The comb plate tool 3 is used for at least one of the first comb plate tool 3a and the second comb plate tool 3b of the comb plate tool 1.

According to such a configuration, when the string material X1 tries to invade the seam 5, the string material X1 is pulled toward the first lateral direction D1, whereas the string material X1 is pulled inside the first lateral direction D1 of the seam 5. The end portion 51 extends so as to intersect the first lateral direction D1 in the vertical direction D3 view. As a result, the direction in which the string material X1 is pulled is different from the direction in which the inner end portion 51 of the first lateral direction D1 of the seam 5 extends, so that it is possible to prevent the string material X1 from invading the seam 5.

Further, in the comb plate tool 1 according to the present embodiment, the inner end portion 51 of the first lateral direction D1 of the seam 5 extends along the second lateral direction D2 in the vertical direction D3. ..

According to such a configuration, since the inner end portion 51 of the first lateral direction D1 of the seam 5 extends along the second lateral direction D2 in the vertical direction D3, the direction in which the string member X1 is pulled is determined. It is orthogonal to the direction in which the inner end 51 of the first lateral direction D1 of the seam 5 extends. As a result, it is possible to effectively prevent the string material X1 from invading the seam 5.
