Claims (1)

[Scope of Claim for Utility Model Registration] 1. Seat A is attached to a seat storage wall D erected on the floor surface via a seat support mechanism so that it can be raised and lowered as well as retracted, and the seat A is taken out in at least two positions, up and down. In a stowable seat that has an elevating function and can be fixed in a horizontal state, the seat support mechanism is disposed inside and below the seat stowage wall D, the lower end is connected to the frame of the seat stowage wall D, and the upper end is connected to the frame body of the seat stowage wall D. A lifting function characterized by comprising a pantograph-type expansion/contraction mechanism R connected to the rear of the seat A via a link mechanism E, and a seat fixing mechanism F that fixes the pantograph-type expansion/contraction mechanism R in two positions, up and down. Has a retractable seat. 2. The retractable seat with an elevating and lowering function according to claim 1, wherein the seat fixing mechanism F is a driving means for expanding and contracting the pantograph type expanding and contracting mechanism R.
