PROBLEM TO BE SOLVED: To provide an easy-to-perform reaction force suppression means in a simple mechanism with a sufficient reaction force suppressing effect of suppressing push-up reaction force N<SB>1</SB>acting on the body from one left or right side of an elastic fabric whose sinking amount is reduced and which is placed in a relatively floating state when a posture is inclined in a seat for which a seat surface is constituted by spreading the elastic fabric between a left side frame material and a right side frame material. SOLUTION: The seat surface 14 is constituted by spreading the elastic fabric 13 between the left side frame material 11 and the right side frame material 12 supported by a seat frame 16. One end of elastic pull-in materials 15a and 15b is joined respectively to the left and right of the back surface of the intermediate part of the elastic fabric 13 held by the left side frame material 11 and the right side frame material 12. The respective other ends of the left and right elastic pull-in materials 15a and 15b are turned to directions opposite to each other and respectively joined to the seat frame 16.
