Abstract
A lead screw nut support arrangement includes a wall having a width and a through hole that passes through the wall. A support bushing passes through the through hole in the axial direction, leaving an amount of play, and having a length greater than the thickness of the wall. The support bushing is supported in the through hole movably in the axial direction. A lead screw nut is also included whose end face adjoins a first end face of the support bushing on the inner side of the wall. The support arrangement also includes a mount that braces a second end face of the support bushing against the lead screw nut such that the lead screw nut is elastically loaded in the direction away from the wall.
