第1項記載の椅子。[Claims for Utility Model Registration] 1. A movable member with a seat plate attached to the top surface is disposed substantially parallel to the upper part of a frame consisting of a long box body with an upward opening that can be attached to a footrest, and said frame one end of the front link member is pivotally attached to an appropriate position on the frame, the other end located forward of the pivoting position is pivotally attached to the front end of the movable member, and one end of the rear link member is pivotally attached to an appropriate position on the frame. At the same time, the other end disposed rearward from the pivot position is pivotally connected to the rear end of the movable member, and further a backrest rod having a backrest plate attached to the upper part is attached to the rear end of the frame. The lower end is pivoted to allow tilting, and the lower end of the backrest lever is connected to the middle part of both pivot points of the rear link member or the rear end of the movable member, and the lower end of the backrest lever is connected to the other side. A long hole into which a floating support shaft can be loosely inserted is formed to connect the connecting rod, or both ends of the connecting rod are connected by pivoting, and both ends of a coil spring are placed in a suitable position on the upper part of the front link member and in a suitable position in the frame. The chair is characterized in that the movable member is elastically biased rearward by connecting the two members, and a stopper is provided at a suitable position within the frame to restrict rearward rotation of the rear link member. 2. The chair according to claim 1, wherein the horizontal distance between the pivot joints at both ends of the rear link member is set larger than the horizontal distance between the pivot joints at both ends of the front link member.
