Claims

[Scope of utility model registration request]

A pinion rotatably supported by a casing, a rack bar having rack teeth that mesh with the pinion, a rack guide that is inside the casing and slidably supports the rack bar, and presses the rack guide toward the rack bar. In a rack and pinion type steering device consisting of a spring, the rack guide is composed of a base body and a sliding piece that is fitted and held in the base body, and the base body has a cylindrical outer circumferential surface and a cylindrical surface at one end. A concave curved part is provided at one end, and a hollow cylindrical part is provided at the other end, and a circular hole communicating with the hollow cylindrical part is provided at the bottom of the concave curved part, and a curved part is provided at the periphery of the concave curved part. A band-shaped protrusion of uniform height is formed along the curved surface of the concave surface, and the sliding piece is composed of a thin steel plate and a porous sintered material integrally formed on the thin steel plate. The metal layer and the sintered metal layer are impregnated with a coating material such as a synthetic resin, a part of which is formed as a thin layer on the sintered metal layer, and the sliding piece is made of synthetic resin. It has an arcuate inner and outer peripheral surface formed with the layer on the inside, and a protrusion formed integrally with the outer circumferential surface, and the sliding piece presses the protrusion into the circular hole of the concave curved dust. A rack and pinion type steering device characterized in that the sliding piece is fitted into the concave curved surface of the concave curved surface so that the inner circumferential surface of the sliding piece protrudes from the band-shaped protrusion and is held therein.
