Abstract
Proposed is a rack guide which achieves both a stable feed of a lubricant from a rack bar to a lubricant retaining groove and a stable supply of the lubricant from the lubricant retaining groove to the rack bar when the rack bar slides against the rack guide. At least one pair of lubricant retaining grooves configured to retain a lubricant interposed between a rack bar and a supporting surface and face each other in a rack guide longitudinal direction extend in a rack guide transverse direction perpendicular to the rack guide longitudinal direction and are arranged on the supporting surface in such a shape as to bulge away from each other in the rack guide longitudinal direction. An apex of each of the lubricant retaining grooves in the rack guide longitudinal direction is located in a contact area.
