オン式ステアリング装置。[Claims for Utility Model Registration] A cylindrical synthetic resin rack guide is provided in the housing and is pressed against the rack rod by a spring to guide it and apply preload between the rack and pinion. In a rack and pinion type steering device in which a guide groove for guiding a rack rod is formed in the rack guide, a circular spring housing hole and an annular groove located outside the hole are concentrically formed on the end surface of the rack guide opposite to the guide groove. The rack guide is formed into a double cylindrical shape with an inner cylinder part and an outer cylinder part, and has a plurality of ribs in an annular groove between the inner cylinder part and the outer cylinder part, which are parallel to the guide groove. Ribs are provided in the diametrical direction, and the end surface of the inner cylinder portion is flush with or protrudes from the end surface of the outer cylinder portion, and the end surface of the rib parallel to at least the guide groove in the annular groove is aligned with the end surface of the inner cylinder portion. A rack and pinion type steering device characterized by being flush.
