PROBLEM TO BE SOLVED: To provide an operation support apparatus that supports operation while allowing displacement of a wearing position.SOLUTION: An operation support apparatus 1 is worn in a first region at one side of a wearer's joint and a second region at the other side, and supports the joint operation. The operation support apparatus includes: a joint mechanism 16 arranged in the vicinity of the joint, and driven by an actuator； a frame 12 with one end connected to the joint mechanism 16, the frame 12 that has a portion unlike the one end among the frames 12 being worn in the first region； a connecting body 22 with one end connected to the frame 12 in a turning manner around the turning shaft J by the joint mechanism 16, the connecting body 22 that has a portion unlike the one end among the connecting bodies 22 being worn in the second region； and a connecting body 18 where a portion is connected to the joint mechanism 16 or the frame 12 so as to move substantially in a circumferential direction centering on the turning shaft J, the connecting body 22 that has the other portion unlike the portion of the above among the connecting bodies 18 being worn in a third region unlike the first region and the second region of a wearer.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2019,JPO&INPIT【課題】装着位置のずれを許容しながら動作支援をする。【解決手段】装着者の関節の一方側にある第一部位と、他方側にある第二部位とに装着され、上記関節の動作を支援する動作支援装置１は、上記関節の近傍に配置され、アクチュエータによって駆動される関節機構１６と、一端が関節機構１６に接続されるフレーム１２であって、フレーム１２のうち上記一端と異なる一部が上記第一部位に装着されるフレーム１２と、一端が関節機構１６によって回動軸Ｊ周りに回動可能にフレーム１２に接続される接続体２２であって、接続体２２のうち上記一端と異なる一部が上記第二部位に装着される接続体２２と、一部が回動軸Ｊを中心として略円周方向に移動可能に関節機構１６又はフレーム１２に接続される接続体１８であって、接続体１８のうち上記一部と異なる他の一部が、装着者の上記第一部位及び上記第二部位と異なる第三部位に装着される接続体２２とを備える。【選択図】図１
