PROBLEM TO BE SOLVED: To make it possible to support body motion while achieving downsizing and weight saving.SOLUTION: A wearable motion support unit SU comprises: a first support member 10 attached to an upper arm part A1 and a second support member 12 which is attached to a forearm part A2 and is connected to the first support member 10, and whose posture can be displaced according to bending and stretching motion of an elbow joint A3 sandwiched between the first support member 10 and second support member 12. The first support member 10 includes a main body 20 having restriction means 14 capable of being displaced into a restriction state where the posture displacement of the second support member 12 is restricted and a restriction release state where the posture displacement is allowed. The second support member 12 includes detection means 16 for detecting motion of the forearm part A2 and transmitting a detection signal to control means. The restriction means 14 is displaced into the restriction state and restriction release state by actuators 86, 87 controlled by the control means receiving the detection signal from the detection means 16.COPYRIGHT: (C)2015,JPO&INPIT【課題】小型軽量化を図りつつ身体動作を補助可能とする。【解決手段】装着型動作補助装置SUは、肘関節A3を挟む上腕部A1に装着される第1サポート部材10と、前腕部A2に装着されると共に第1サポート部材10に連結され、肘関節A3の屈伸動作に合わせて姿勢変位可能な第2サポート部材12とを備える。第1サポート部材10の本体部20には、第2サポート部材12の姿勢変位を規制する規制状態および姿勢変位を許容する規制解除状態に変位可能な規制手段14が設けられる。第2サポート部材12には、前腕部A2の動きを検知して制御手段に検知信号を送出する検知手段16が設けられる。規制手段14は、検知手段16からの検知信号を受けた制御手段により制御されるアクチュエータ86,87により、規制状態および規制解除状態に変位する。【選択図】図2
