The invention relates to a seat back adjusting mechanism. The seat back adjusting mechanism comprises chair back frames, air springs, locking units and chair seat frames. One ends of the air springs are connected with the chair back frames, and the other ends of the air springs are connected with chair seat frames; one ends of the locking units are connected with the chair back frames, and the other ends of the locking units are in pin connection with the chair seat frames; each locking unit comprises a steel ball, a pressing block, a steel cable, an adjusting rod, a lock frame, a convex head and a pressure spring; the convex heads are arranged in the lock frames; and the right ends of the convex heads are sleeved with the pressure springs, and the left ends of the convex heads are in contact with the steel balls. The adjusting rods penetrate through holes of the convex heads, and a plurality of grooves are formed in each adjusting rod; and the steel balls are clamped between the lock frames and the rear ends of the pressing blocks, and the steel cables are arranged at the front ends of the pressing blocks. The adjusting mechanism is small in size, reliable in performance and convenient to maintain. When other parts need to be installed on the rotating position of a seat back or an angular adjuster cannot be mounted, the back adjusting mechanism can be used.
