PROBLEM TO BE SOLVED: To solve problems for example, when a base member of a lift device is made light, the lift device is fallen due to weight of an assisted person, and when the base member is made heavy, a space for storing the lift device cannot be saved during non-use time.SOLUTION: A base member 20 comprises at least two plates which are disposed to be overlapped in a vertical direction, and a left and right pair of leg members 24 are detachably attached to openings between the vertical plates. A left and right pair of handles 32 are attached to be linked to the leg members, a pedal 28 is disposed between lower parts of the handles, and a left and right pair of wires 36 are extended between the pedal and lower parts of the handles, respectively. A lateral direction interval between a left and right pair of insertion holes 28Fr on a front side of the pedal is shorter than an interval of a left and right pair of insertion holes 28Rr on a rear side, and the left and right pairs of insertion holes on the front and rear side correspond to opening/closing positions of leg members and initial positions of leg members respectively. A length of a rear end of the wire which is folded downward is shorter than a depth of stepping of the pedal. When the pedal is stepped, the wires are withdrawn from the insertion holes, and when the handles are oscillated, the leg members are oscillated through the wires.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2017,JPO&INPIT
