< Topic >It makes operational of the finger joint possible with simple structure, for example it can allow the load load to the finger joint in the general job such that holds down the paper, grasps, the cheap artificial finger is offered.SolutionsAt least the second component which possesses the length which possesses the first component and the convex section or the crevice which possess the length which possesses the crevice or the convex section of 2 places and, being the artificial finger which is included, the first component and the second component, length direction revolution possibly and mutually it is concatenated to the abbreviation vertical axis to length direction Y of X of the first component and the second component. Furthermore, standards 14 for the first component are interposed in complete penetration section, 26 standards 14 for the first component and standards 24 for the second component, are concatenated by elastic body 32. The second component can be locked with optional angle the crevice of the first component or by checking and verifying the convex section or the crevice of the second component in either of the convex sections, vis-a-vis the first component.< Choice figure >Drawing 5【課題】簡易な構造で指関節の可動を可能とし、例えば紙を押さえる、掴む等の一般的な作業における指関節への荷重負荷を許容し得る、安価な義指を提供する。【解決手段】少なくとも2箇所の凹部又は凸部を具備した長さを有する第一部材と、凸部又は凹部を具備した長さを有する第二部材と、を含む義指であって、第一部材と第二部材とは、第一部材の長さ方向X及び第二部材の長さ方向Yに略垂直な軸に回転可能に、互いに連結されている。さらに、第一部材用支柱14は貫通部26に挿入され、第一部材用支柱14と第二部材用支柱24とは、弾性体32によって連結されている。第一部材の凹部又は凸部のいずれかに第二部材の凸部又は凹部を勘合させることにより、第一部材に対して第二部材を任意の角度で固定できる。【選択図】図5
