A backrest adjusting mechanism is angularly disposed between a backrest and a seat of a chair, and includes a main support slidably received in a sleeve member, and a locating gear. The main support is provided on a middle lower surface with a downward projected limiting element and on a middle upper surface with an elastically upward protruded locating element. The sleeve member is provided on a lower surface with a lengthwise guide slot for the limiting element to slide therein, and on an upper surface with locating recesses for the elastic locating element to slide thereinto and hold the main support to an adjusted position. The locating gear includes a shaft turnably extended across the sleeve member, so that a press lug of at least one brake element on the shaft may be turned to firmly press against and hold the main support in place at the adjusted position.
