Abstract

PURPOSE:To provide a comfortable ride by mounting a device which is elevated up or down by turning a control lever and adjusting a height of a lumber plate to support the third articulate part. CONSTITUTION:By turning a control lever 22, a cam member 24 is turned to shift the internal end of a depression regulating plate 4 forward with respect to a pin 12. Associated with said forward shift, a lumber plate 1 is moved forward by means of an elastic support plate 4' to a regulated point which depends on a stopped position of the cam member 24. Then by pulling a position control lever 6 up or down, parallel link levers 2, 3 connected with the position control lever 6 by a link 19 are shifted up or down so that the elastic support plate 4' and the lumber plate 1 make an up or down motion.
