PROBLEM TO BE SOLVED: To provide a support device and a bathing support device which can be easily operated by an assistant.SOLUTION: A bathing support device 1 is configured so that: a support member 36 has a rotation axis part 38 for rotating a handrail member 8a the rotation axis part 38 is connected to the handrail member 8a so that the handrail member 8a is rotated between a first position X1 where an assistant can contact and operate the handrail member and the handrail member comes close to a stool member 2 and a second position X2 where the handrail member is engaged by an engagement mechanism 9 and is separated from the stool member 2 and the assistant. The rotation axis R is provided so that an angle θ1 formed of a cross line L which crosses to a line connecting positions having a shortest distance from an attachment position on the support member 36 to a side where the assistant operates, and the rotation axis R is a sharp angle.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2017,JPO&INPIT【課題】補助者が操作しやすい支援装置及び入浴支援装置を提供すること。【解決手段】入浴支援装置1において、支持部材36は、手摺部材8aが回動する回動軸部38を有し、回動軸部38は、手摺部材8aが、補助者が接触して操作可能であって腰掛部材2に近接する第1位置X1と、係止機構9によって係止され、腰掛部材2および補助者から離間した第2位置X2との間を回動するように、手摺部材8aと接続し、その回動軸Rが、支持部材36における取付位置から補助者が操作する側への最短距離となる位置を結ぶ線に対して交差する交差線Lと回動軸Rとのなす角θ1が鋭角となるように設けられている。【選択図】図3
