PROBLEM TO BE SOLVED: To allow an assist force to act on a wearer efficiently by effectively preventing the movement of a mounting fixture with respect to the wearer and deformation of the mounting fixture.SOLUTION: A mounting fixture 40 includes: a connection part 53 connected to a force generation part 20 which generates a force to assist the action of the body of a wearer H; a fixing part 60 for fixing the connection part to the body of the wearer; and a deformation suppression part 55 for suppressing the deformation of the fixing part caused by a reaction force of the force which the force generation part has generated. The deformation suppression part 55 is arranged in an intermediate position in the fixing part from the connection part up to the position opposing to the connection part by sandwiching the body of the wearer.SELECTED DRAWING: Figure 8COPYRIGHT: (C)2020,JPO&INPIT【課題】装着具の着用者に対する移動や装着具の変形を効果的に防止して、アシスト力を効率的に着用者に作用させることを目的とする。【解決手段】装着具40は、着用者Hの体の動作を補助する力を発生する力発生部20と接続する接続部53と、接続部を着用者の体に固定する固定部60と、力発生部が発生した力の反力による固定部の変形を抑制する変形抑制部55と、を有する。変形抑制部55は、接続部から着用者の体を挟んで接続部に対向する位置に至るまでの間の固定部における中間位置に配置される。【選択図】図8
