A drawer pull-out guide, comprising: - a carcass rail configured to be fixed to a furniture carcass, - at least one fastening portion for fixing the carcass rail to the furniture carcass, the at least one fastening portion having a vertical limb configured to bear against the furniture carcass and a transverse limb protruding from the vertical limb, wherein the transverse limb of the fastening portion is connected to a limb of the carcass rail, the limb of the carcass rail extending in a longitudinal direction of the carcass rail, - at least one extension rail displaceably supported relative to the carcass rail in the longitudinal direction, - at least one rolling body (21a, 21b, 21c) arranged between the carcass rail and the extension rail, the at least one rolling body (21a, 21b, 21c) being supportable on a running limb (22a, 22b, 22c, 22d) of the carcass rail and/or of the at least one extension rail, - wherein the limb of the carcass rail includes a first limb portion and at least one second limb portion, the first limb portion of the carcass rail being connected to the transverse limb of the fastening portion, and the second limb portion is configured to be tilted or bent about an axis extending in a longitudinal direction upon a load of the extension rail, so that a change of the relative position between the running limb (22a, 22b, 22c, 22d) and the rolling body (21a, 21b, 21c) in a direction extending transversely to the longitudinal direction is at least partially compensated for, - wherein the second limb portion of the carcass rail is arranged closer to the vertical limb than the first limb portion, and wherein a width of the second limb portion, measured in a direction extending transversely to the longitudinal direction, is at least twice a width of the first limb portion, characterized in that the first limb portion and the second limb portion, in a mounted condition, are spaced apart from each other in a height direction in a parallel relationship. - a carcass rail configured to be fixed to a furniture carcass, - at least one fastening portion for fixing the carcass rail to the furniture carcass, the at least one fastening portion having a vertical limb configured to bear against the furniture carcass and a transverse limb protruding from the vertical limb, wherein the transverse limb of the fastening portion is connected to a limb of the carcass rail, the limb of the carcass rail extending in a longitudinal direction of the carcass rail, - at least one extension rail displaceably supported relative to the carcass rail in the longitudinal direction, - at least one rolling body (21a, 21b, 21c) arranged between the carcass rail and the extension rail, the at least one rolling body (21a, 21b, 21c) being supportable on a running limb (22a, 22b, 22c, 22d) of the carcass rail and/or of the at least one extension rail, - wherein the limb of the carcass rail includes a first limb portion and at least one second limb portion, the first limb portion of the carcass rail being connected to the transverse limb of the fastening portion, and the second limb portion is configured to be tilted or bent about an axis extending in a longitudinal direction upon a load of the extension rail, so that a change of the relative position between the running limb (22a, 22b, 22c, 22d) and the rolling body (21a, 21b, 21c) in a direction extending transversely to the longitudinal direction is at least partially compensated for, - wherein the second limb portion of the carcass rail is arranged closer to the vertical limb than the first limb portion, and wherein a width of the second limb portion, measured in a direction extending transversely to the longitudinal direction, is at least twice a width of the first limb portion,
