The pushchair has two rear upright tubes (71) each connected by an upper end to a handle (3), and two auxiliary tubes (72) installed adjacent to the upright tubes, whereby an upper end of each auxiliary tube is rigidly connected to a joint (73), and the lower end movably extends through another joint (74). Two seat tubes (4) are connected to the lower end of the auxiliary tubes, and two seat back tubes (5) are hinge-connected to the seat tubes. A support plate interconnects the seat back tube and rear leg tube (9) on the same side as the seat back tube.
