PROBLEM TO BE SOLVED: To provide a finger bending correction tool capable of appropriately eliminating finger bending and improving the aesthetic appearance of a finger. SOLUTION: A guide member 2 having a concave cross section and a long shape and a leaf spring 3 provided on the inner side surfaces of left and right walls 2a and 2b of the concave guide member 2 and urging the tip of a finger It is provided. In order to fix the finger with tape or bandage, it is preferable that the upper surface of the guide member 2 is lower than the upper surface of the inserted finger when the finger is inserted into the recess of the guide member 2. It is mainly used for the middle finger because the deformation of the middle finger caused by improper gripping of the pencil is the point of interest. By interposing a spacer between the finger of the second joint and the left and right walls 2a and 2b, the position of the second joint may be constrained. [Selection diagram] Fig. 1【課題】指曲がりを適切に解消し、指の美観を改善することができる指曲がり矯正具を提供する。【解決手段】断面凹形状かつ長尺状のガイド部材2と、該凹形状のガイド部材2の左右壁2a、2bの内側面に設けられ指の先端部を付勢する板バネ3と、が設けられている。指をテープや包帯で固定するために、ガイド部材2の凹部に指を挿入した場合にガイド部材2の上面が挿入した指の上面より低い位置にくるようにすることが好ましい。不適切な鉛筆の握り方によって発生する中指の変形が着目点であるため、主に中指に利用される。第2関節の指と左右壁2a、2bとの間にスペーサーを介在させると、第2関節の位置を拘束できて良い。【選択図】図1
