A pair of backrest conversion devices configured on both sides of the chair, each of the backrest conversion devices having a guide hole at the upper end side of a pair of guide links whose lower ends are rotatably pivoted at the center of the side frame of the futon holder. and insert pin shafts projecting apart from the lower end of the backrest frame into the guide holes so as to be slidable in the hole direction, and insert both pin shafts protruding from the guide holes into the futon. The guide groove is slidably and loosely fitted into a substantially arc-shaped guide groove having a relatively large radius of curvature, which is formed in a guide plate fixed to the back side of the armrest armrest fixed to both side frames of the receiver. The converting device for a backrest converting chair is characterized in that the backrest is supported by the guide groove, and the backrest is moved and displaced from one end of the guide groove to the other end to change the orientation of the chair. .
