PROBLEM TO BE SOLVED: To provide a yarn holder that can hold yarn easily.SOLUTION: A yarn holder has a pair of elastic boards 13a,13b having cushioning properties and a pair of pressing members 30a, 30b with the rigidity higher than that of the elastic boards 13a, 13b. The elastic boards 13a, 13b are sandwiched between pressing members 30a, 30b. At least one side of the pressing members 30a, 30b has an area smaller than the elastic boards 13a, 13b, and at least one side of the elastic boards 13a, 13b is recessively changed by the pressing force of the pressing members 30a, 30b. An area t sandwiched between the pair of pressing members 30a, 30b of the pair of elastic boards 13a, 13b is brought into strong contact, and the other part is opened or comes into a loose contact.SELECTED DRAWING: Figure 8COPYRIGHT: (C)2017,JPO&INPIT【課題】容易に糸を保持させることができる糸の保持具を提供することである。【解決手段】 クッション性を有する一対の弾性板13a,13bと、弾性板13a,13bよりも剛性が高い一対の押圧部材30a,30bを有し、弾性板13a,13bが、押圧部材30a,30bの間に挟まれており、押圧部材30a,30bの少なくとも一方は、面積が弾性板13a,13bよりも小さく、押圧部材30a,30bの押圧力によって弾性板13a,13bの少なくとも一方が凹変しており、一対の弾性板13a,13bの、一対の押圧部材30a,30bで挟まれた領域tは強く接し、その他の部位は開いているか又は緩く接している。【選択図】図8
