A drawer pull-out guide, comprising: - a carcass rail 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 rest 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 configured to be supported on a running limb (22a, 22b, 22c, 22d) of the carcass rail and/or on a running limb (22a, 22b, 22c, 22d) of the at least one extension rail, - wherein the limb of the carcass rail has 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 of the carcass rail, in an unloaded condition of the drawer pull-out guide, is spaced from the transverse limb of the fastening portion by the formation of a gap and can be tilted or bent in a direction towards the transverse limb about an axis extending in the 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), caused by a load of the extension rail in a direction transverse to the longitudinal direction, is at least partially compensated for, wherein the second limb portion is arranged closer to the vertical limb than the first limb portion, characterized in that the size of the gap located between the second limb portion of the carcass rail and the transverse limb of the fastening portion can be reduced upon the load of the extension rail, wherein the first limb portion of the carcass rail is connected, preferably welded, to the transverse limb of the fastening portion by at least one fastening location (23a, 23b), wherein the carcass rail, in that way, can be bent or tilted about the longitudinal direction relative to the transverse limb of the fastening portion. - a carcass rail 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 rest 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 configured to be supported on a running limb (22a, 22b, 22c, 22d) of the carcass rail and/or on a running limb (22a, 22b, 22c, 22d) of the at least one extension rail, - wherein the limb of the carcass rail has 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 of the carcass rail, in an unloaded condition of the drawer pull-out guide, is spaced from the transverse limb of the fastening portion by the formation of a gap and can be tilted or bent in a direction towards the transverse limb about an axis extending in the 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), caused by a load of the extension rail in a direction transverse to the longitudinal direction, is at least partially compensated for, wherein the second limb portion is arranged closer to the vertical limb than the first limb portion, characterized in that the size of the gap located between the second limb portion of the carcass rail and the transverse limb of the fastening portion can be reduced upon the load of the extension rail, wherein the first limb portion of the carcass rail is connected, preferably welded, to the transverse limb of the fastening portion by at least one fastening location (23a, 23b), wherein the carcass rail, in that way, can be bent or tilted about the longitudinal direction relative to the transverse limb of the fastening portion.
