Abstract
In a rack and pinion type steering gear device having a rack guide to urge a rack from behind for applying a preload to the meshing engagement of tooth surfaces of the rack and pinion, wherein the rack guide is formed of an oleoresinous material having a low coefficient of friction and elastically deformable to a compression load to a predetermined value. The rack guide can bear a high load as compared with the conventional rack guide for the same displacement value, so that the rack guide can have a resisting force of a high value. Because of this, the pinion and the rack which are urged by the rack guide are not easily separated from each other under an external force. The rack guide preferably includes a guide body having a rack sliding surface and outer peripheral ribs, and an elastic ring having the bottom end portion extending towards a nut farther by a predetermined value than the bottom end portion of said outer peripheral ribs and being elastically deformable to a compression load.
