Disclosed can support their own body, with or leaning, by an assistant device used for waking-in bed, standing, sitting, assisting walking and the like, and depending on the users needs, horizontal position, vertical Position and Select horizontal angle and secure the assistance auxiliary bodies, by changing to a different location or angle needed to provide an assistance device and its assistance auxiliary member may be used to assist in the operation. A body B is, both the post portion B1, upper horizontal connecting portions B2, consisting of the upper middle horizontal coupling portion B3a, under intermediate horizontal connection portion B3b and vertical coupling portion B4. Thereby upright supporting the body B to base D by coupling the base of both the struts B1 to the fixed portion D1. Assistance auxiliary body C comprises a pair of rod-shaped body C1, the rod-shaped coupling portion C2 and the fixed portion C3. The fitted onto the fixed portion C3, it is divided in the circumferential direction to the support part B1 or vertical connection portion B4, a division location by screws fastened and fixed to the support portion B1. .BACKGROUND【課題】自身の身体を支持したり、もたれたりして、起床・就床・起立・着座・歩行等の補助に用いる介助装置であって、使用者の必要に応じ、水平方向位置、上下方向位置及び水平方向角度を選択して介助補助体を取り付けて固定し、必要に応じ別の箇所又は角度に変更して、動作の補助に使用し得る介助装置及びその介助補助体を提供する。【解決手段】本体Bは、両支柱部B1、上部水平連結部B2、上中間水平連結部B3a、下中間水平連結部B3b及び垂直連結部B4からなる。両支柱部B1の基部を固定部D1に連結することにより本体Bを基盤Dに対し起立支持させる。介助補助体Cは、一対の棒状体C1、棒状連結部C2及び固定部C3を備える。周方向に分割した固定部C3を支柱部B1又は垂直連結部B4に外嵌し、分割箇所を螺子締め固定することにより、支柱部B1に対し固定する。【選択図】図1
