PROBLEM TO BE SOLVED: To provide a lifting device of a seat member having a high degree of freedom in layout of an installation position of a drive source as well as layout of an entire device.SOLUTION: A lifting device 1 of a seat member comprises: a seat member 2; a link mechanism 3 for elevating and lowering the seat member 2 through a path which is curved in at least one portion; a guide member 4 for guiding the seat member 2; and a drive unit 5 for driving the seat member 2. The drive unit 5 comprises: a drive part 51 which is attached to the link mechanism 3 directly or indirectly and extends and contracts by a fluid; and a circulation tube 52 which is connected to the drive part 51 and in which the fluid from a fluid source is circulated. The link mechanism 3 is at least extended by the extension or contraction of the drive part 51, and the seat member 2 is driven. The seat member 2 reciprocates between an upper side of a top edge of a bathtub edge and a position closer to a bathtub bottom part than the top edge of the bathtub edge.SELECTED DRAWING: Figure 1 |
