PROBLEM TO BE SOLVED: To provide a nail corrective apparatus which can be easily attached to a nail of any kind, regardless of difference in curved shape or size, or even presence of a severe inflammation, not being subject to stress, by overcoming defects in conventional, widely-known techniques, and which does not start functioning as a nail corrector until it is installed.SOLUTION: A tensile element (3), which is immovably embedded in an attachment element (1) in marginal areas (2a and 2b) of an attachment element (1) and is projecting from the attachment element (1), is designed to apply adjustable and controllable tensile force for conveying bending moment caused by an eccentric action to a nail plate.COPYRIGHT: (C)2009,JPO&INPIT【課題】公知先行技術の欠点を克服し、酷い炎症時であっても容易に種々異なる湾曲およびサイズに応力無しで爪に取り付けることができ、当該装置の作用が、組み付けた状態で初めて発揮されるようにする。【解決手段】接着エレメント(1)の縁部領域(2a,2b)において前記接着エレメント(1)の材料内に不動に埋め込まれている、前記接着エレメント(1)から進出している引張エレメント(3)によって、偏心的な力作用により曲げモーメントを前記爪甲に伝達する調整可能で規定可能な引張力を加えるようにした。【選択図】図1
