Patent ID: 7908748

Claim:
A method of manufacturing a rack and pinion type steering device comprising a rolling type rack guide including a rack guide holder that presses a back surface of a rack shaft toward a meshed surface of a rack and a pinion by the aid of a roller, the roller having a hand drum shaped outer peripheral surface which is rotatably installed on a pin which is disposed in a pin insertion groove of the rack guide holder, the method comprising the steps of: forming the hand drum shaped outer peripheral surface of the roller with a curvature different from a curvature of an outer peripheral surface of the rack shaft opposite a meshed surface of the rack shaft, pressing the rack shaft toward the formed hand drum shaped outer peripheral surface of the roller, and reciprocating the rack shaft in the axial direction causing the roller to rotate and the hand drum shaped outer peripheral surface of the roller to be plastically deformed, whereby the hand drum shaped outer peripheral surface of the roller is formed in a configuration that comes in line contact with the outer peripheral surface of the rack shaft opposite the meshed surface of the rack shaft.
