(EN) According to the present invention, a front arm part that is a second member can rotate between an in-use position and a standby position on a side frame part that is a first member that is to be arranged in the vicinity of a sitting toilet or the like. A connection member of the front arm part is rotatably held on a connection bracket that is fixed to the side frame part. The rotation of the front arm part can be locked, for example, in the standby position by a swing lever that is swingably held by the connection bracket. The locking occurs as a result of a first locking part, such as a locking groove, that is formed on an outer circumferential surface of the connection member 33 being engaged by a second locking part of the swing lever.
(ZH) 相对于配设于例如坐式马桶的附近的作为第一部件的侧方框架部，作为第二部件的前方臂部能够在使用位置和待避位置之间转动。前方臂部的连结部件能够转动地保持于固定于侧方框架部的连结支架。通过能够摆动地保持于连结支架的摆动杆，前方臂部的转动在例如待避位置被锁定。使摆动杆的第二卡定部卡定于形成于上述连结部件(33)的外周面的第一卡定部、例如卡定槽，由此进行上述锁定。
