PROBLEM TO BE SOLVED: To change the attitude of a lower half body through reclining and to change the angle of upper and lower half bodies. SOLUTION: A link mechanism for linking a seat part 1 and a backrest part 2 is composed of a supporting metal fixture 10 fixed on the seat part 1, link 11 connecting one end to the supporting metal fixture 10, supporting metal fixture 12 fixed on the backrest part 2, and link 13 connecting one end to the supporting metal fixture 12. Then, the other end of the link 11 is connected to the link 13, and the other end of the link 13 is connected through a long hole 13a at that other end to a frame 5. The angle change of the seat part 1 is made smaller than the angle change of the backrest part 2 (θ1 >θ2 ).
