SOLUTION: A jaw correcting jig for straightening a deformable nail, comprising: a wire part integrally formed of a polymer material and having elasticity and having a needle-like tip formed at one end thereof a wire material part formed on the other end of the wire part And a needle-like tip of the wire rod portion is inserted from the back side of the nail tool in a front side direction to a first hole formed at one end in the width direction of the nail plate, The stopper moves the surface along the nail bed until it engages with the back side of the nail plate, and moves the needle-like portion of the wire part toward the second hole formed at the other end in the width direction of the nail plate The tip end is inserted from the front side to the back side of the nail plate and the middle part of the wire part is moved until it follows the surface of the nail plate and the wire part exposed on the back side of the nail plate is made to follow the back side of the nail plate After bending, cut excess part. The shape, size and elasticity are optimized so as to be mounted as described above.(FIG.【解決手段】 変形爪を矯正する爪矯正用治具であって、ポリマー材料により一体成形され、弾性を有しその一端に針状先端が成形されてなる線材部と、この線材部の他端に成形された扁平形状の係止部とを備え、爪甲の幅方向一端に形成された第1の孔に対し、上記線材部の前記針状先端を前記爪甲の裏側から表側方向に挿通させ、上記係止部がその表面を爪床に沿わせて爪甲の裏側に係止するまで移動させると共に、爪甲の幅方向他端に形成された第2の孔に対し、上記線材部の前記針状先端を前記爪甲の表側から裏側方向に挿通させ、線材部の中途部が爪甲の表面に沿うまで移動させると共に、爪甲の裏側に露出した線材部を爪甲の裏側に沿わせて折曲したのち余剰部分を切断する。以上のように装着されるべく形状、寸法、弾性が最適化されている、ものである。【選択図】 図2
