1. A differential drawer slide for furniture parts that can be pulled out, comprising a body rail that can be attached to a furniture body, a pull-out rail that can be attached to a pull-out furniture part and a central rail arranged between the body rail and the pull-out rail, wherein the pull-out rail and the central rail can be pulled out starting from a closed position of the differential drawer slide into an open position of the differential drawer slide in a pull-out direction and the pulling out of the central rail from the body rail in the open position of the differential drawer slide is limited by a stop element of the body rail to which a stop surface of the central rail approaches, wherein on the central rail in the region of the rear end of the central rail an adjustment part is mounted adjustably between a release position in which the central rail can be tilted with respect to the body rail about a horizontal axis located at right angles to the pull-out direction of the central rail from a normal position into a tilt position in which its rear end is lowered with respect to the normal position and for removal of the central rail from the body rail, the stop surface of the central rail can be guided past the body rail under the stop element of the body rail, and a locking position in which the central rail is blocked from any tilting from the normal position into the tilt position, and wherein a lateral guide roller is rotatably mounted on a base body of the adjustment part, which lateral guide roller cooperates with a vertical web of the body rail, wherein the central rail is configured to be shorter than the body rail and shorter than the pull-out rail and in the inserted state of the differential drawer slide, the rear end of the central rail is offset towards the front with respect to the rear end of the body rail and with respect to the rear end of the pull-out rail and that the lateral guide roller of the adjustment part cooperates with a vertical web of the pull-out rail on the side of the adjustment part opposite to the vertical web of the body rail or that on the base body of the adjustment part, an additional lateral guide roller is additionally rotatably mounted which cooperates with the vertical web of the pull-out rail on the side of the adjustment part opposite to the vertical web of the body rail.
