The joint portion 51 extends from the bottom portion 34a of the recess 34 toward the outside in the first lateral direction D1. The joint portion 51 has rigidity so as not to be deformed. As a result, since the joint portion 51 stops the string material X1, it is possible to prevent the string material X1 that has invaded the recess 34 from invading the seam portion 5.

However, the string material X1 may invade the joint portion 51. Therefore, the dimension W1 in the first lateral direction D1 of the joint portion 51 is preferably equal to or less than the dimension W2 in the second lateral direction D2 of the opening 52. As a result, since the dimension W1 of the first lateral direction D1 of the joint portion 51 is small, when the string material X1 invades the joint portion 51, the string material X1 easily passes through the joint portion 51 and invades the opening 52. Therefore, it is possible to prevent the string material X1 from being pinched by the joint portion 51.

The dimension W1 in the first lateral direction D1 of the joint portion 51 and the dimension W2 in the second lateral direction D2 of the opening 52 are not particularly limited. For example, the dimension W2 of the opening 52 in the second lateral direction D2 is preferably 1.5 mm or more, and 2.0 mm or more so that the string member X1 can freely move inside the opening 52. It is more preferable to have.

Therefore, it is possible to prevent the string material X2 that has invaded the seam portion 5 from being sandwiched between the first comb plate tool 3a and the second comb plate tool 3b by invading the opening 52. Can be done. As a result, the string material X2 can freely move inside the opening 52, so that the string material X2 can be pulled out from the opening 52.

It has 36. The concave portion 36 is connected to the outside of the first lateral direction D1 of the convex portion 35. The opening 52 is formed by connecting the recesses 36, 36 of the comb plate tools 3a, 3b to each other. The opening 52 has rigidity so as not to be deformed.

Further, the first comb plate tool 3a includes a protruding portion 37 projecting from the base portion 31 toward the second comb plate tool 3b in the second lateral direction D2, and the second comb plate tool 3b has a base portion 31. It is provided with a protruding portion 37 projecting from the first comb plate tool 3a toward the second lateral direction D2. The protruding portion 37 is connected to the outside of the first lateral direction D1 of the recess 36.

The holding portion 53 is formed by joining the protruding portions 37, 37 of the comb plate tools 3a, 3b to each other. As a result, the dimension W2 in the second lateral direction D2 of the opening 52 can be held, so that the string member X2 can freely move inside the opening 52. The holding portion 53 has rigidity so as not to be deformed.

By the way, when the string material X2 inside the opening 52 invades the holding portion 53, the string material X2 is sandwiched between the first comb plate tool 3a and the second comb plate tool 3b. Therefore, the opening 52 extends to the support portion 22 of the plate body 2. As a result, the support portion 22 covers the holding portion 53, specifically, between the protruding portions 37 and 37 of the comb plate tools 3a and 3b from below.

Therefore, even if the string material X2 tries to invade the holding portion 53 through the opening 52, the support portion 22 stops the string material X2, so that the string material X2 can be prevented from invading the holding portion 53. In this way, the string material X1 is suppressed from invading the seam portion 5, and when the string material X2 invades the seam portion 5, the string material X2 is the first comb plate tool 3a and the second comb plate. It is possible to prevent the tool from being sandwiched between the tool 3b and the tool 3b.
