Abstract

Abstract PROBLEM TO BE SOLVED: To optionally select and fix a seat part angle in use by operating a rocking generating device provided on an armrest part by a rocking and fixing operation lever provided on a leg part. SOLUTION: A rocking element is formed of at least two rotating bodies 3 fixed by a rotating body fixture 4, and a connecting plate 5 with a seat part 9 fixed to the rotating body fixture 4. A rocking generating device 1 has this rocking element integrated into a rocking element receiving base 6 having a curvature radius of 13cm. This rocking generating device 1 is set on the upper end of a leg part 8, and the connecting plate 5 with the seat part 9 is connected to the seat part 9. When a rocking fixing operation lever 11 is rotated, a rocking fixing side plate 12 fixed to the connecting plate 5 with the seat part 9 is pressed onto a rocking fixing side pressure receiving tool mounted opposite thereto, and the seat part 9 is fixed at a desired angle. When the rocking fixing operation lever 11 is reversely rotated, the rocking fixing operation lever 11 releases the force pressing the rocking fixing side plate 12, and the seat part 9 is separated from the rocking fixing side pressure receiving tool opposed to the rocking fixing side plate 12, and the seat part is freely longitudinally tilted.
