PROBLEM TO BE SOLVED: To provide a correcting tool mountable without making an excessive force act on the nails, and properly usable for correcting nails having different sizes.SOLUTION: A correcting tool includes: a left side arm 2 including a hooking part 20 to the left side edge part Na of a nail N a right side arm 2 including the hooking part 20 to the right side edge part Nb of the nail N and a fulcrum member 3 between the left side arm 2 and the right side arm 2, having a lower end part as an abutment part 31b to the nail N. The left side arm 2 and the right side arm 2 rotatably combine a forearm part 21 and an upper arm part 22 respectively, have the hooking part 20 on the forearm part 21, and rotatably combine the upper arm part 22 with a base body 1. The fulcrum member 3 includes: a shaft body 30 combined with the base body 1 in an advancing/receding manner in the vertical direction a movable body 31 combined with the shaft body 30 in a vertically movable manner, and forming the abutment part 31b under the shaft body 30 and a compression coil spring 32 interposed between both of them.COPYRIGHT: (C)2014,JPO&INPIT【課題】爪に過剰な力を作用させることなく装着可能で、かつ、寸法を異にする爪の矯正にそれぞれ適切に利用可能な矯正具の提供。【解決手段】爪Nの左側の側縁部Naへの引っかけ部20を備えた左側アーム2と、爪Nの右側の側縁部Nbへの引っかけ部20を備えた右側アーム2と、左側アーム2と右側アーム2との間にあって下端部を爪Nに対する当接部31bとした支点部材3とを有する。左側アーム2及び右側アーム2はそれぞれ、前腕部21と上腕部22とを回動可能に組み合わせてなると共に、この前腕部21に引っかけ部20を持ち、上腕部22をベース体1に回動可能に組み合わせている。支点部材3は、ベース体1に対し上下方向に螺進退可能に組み合わされた軸体30と、この軸体30に上下動可能に組み合わされてこの軸体30下に当接部31bを形成させる可動体31と、両者間に介装された圧縮コイルバネ32とを備える。【選択図】図6
