Abstract
Proposed is a rack guide which achieves a stable feed of a lubricant from a rack bar to a lubricant retaining groove when the rack bar slides against the rack guide. A lubricant retaining groove is arranged in the supporting surface, the lubricant retaining groove being configured to extend in a rack guide transverse direction perpendicular to a rack guide longitudinal direction and retain a lubricant located between a rack bar and a supporting surface. The lubricant retaining groove has a ship-bow-shaped lubricant introducing area into which the lubricant is introduced and a lubricant retaining area connected to the lubricant introducing area and configured to retain the lubricant introduced from the lubricant introducing area. The lubricant retaining area of the lubricant retaining groove is provided in a contact area of the supporting surface.
