PROBLEM TO BE SOLVED: To provide an assisting device capable of reducing load acting on a joint of at least a portion of a wearer.SOLUTION: An assisting device 1 includes elastic support members 11A, 11B and tension belts 12A, 12B. The elastic support members 11A, 11B are to be disposed between a pelvic part A1 and a rib part A2 on an external surface of a human body. The elastic support members 11A, 11B elastically deform to apply a force to the pelvic part A1 and the rib part A2, the force acting in a direction that brings the pelvic part A1 and the rib part A2 away from each other. The tension belts 12A, 12B apply a force to the pelvic part A1 and the rib part A2, the force pulling the pelvic part A1 and the rib part A2 toward a back side of the human body. The elastic support members 11A, 11B and the tension belts 12A, 12B are disposed in such a manner that a composite force of the force acting in the direction that brings the pelvic part A1 and the rib part A2 away from each other and the force pulling the pelvic part A1 and the rib part A2 acts in a direction that extends and stretches a lumbar is.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】装着者の少なくとも1部分の関節に加わる負荷を軽減できる補助具を提供する。【解決手段】補助具1は、弾性支持部材11A、11Bと、テンションベルト12A、12Bと、を備える。弾性支持部材11A、11Bは、人体の外表面の骨盤部A1と肋骨部A2との間に配置される。弾性支持部材11A、11Bは、弾性変形して、骨盤部A1と肋骨部A2とが互いに離れる方向へ作用する力を骨盤部A1と肋骨部A2とに加える。テンションベルト12A、12Bは、人体の背中側へ骨盤部A1と肋骨部A2とを引っ張る力を骨盤部A1と肋骨部A2とに加える。弾性支持部材11A、11Bおよびテンションベルト12A、12Bは、骨盤部A1と肋骨部A2とが互いに離れる方向へ作用する力と、骨盤部A1と肋骨部A2とを引っ張る力と、の合成力が腰椎を伸展かつ伸長させる方向へ作用するように配置されている。【選択図】図1
