Abstract: A drawer fixing apparatus includes a bottom rail on a cabinet and having a movable latch member and at least one slide. The slide has a brake connected to a fixing member by a resilient member and an inner rail slidable on the slide and combined with a drawer. The inner rail includes a driven member having an embedding groove and a movable turning member pivotally connected to the driven member. As the inner rail moves with the drawer into the cabinet, the slide moves accordingly. The brake pushes the driven member to drive the turning member to rotate and press a latch member. When a user releases his/her hand, the resilient member pulls the brake backward slightly to resume the turning member to its original position, while the latch member falls naturally into the embedding groove of the driven member by gravitational force to achieve the positioning effect.
