Claims

[Scope of utility model registration request]

The lower surface of the rack rod that meshes with the pinion that is rotatably supported in the rack housing is supported by a support yoke bearing surface that is pressed by a spring. A rack and pinion type steering device in which the rack rod is supported only by the support yoke receiving surface in the straight-ahead state, and an uneven portion is formed on the lower surface of the rack rod so that the lower surface of the rack rod contacts the outer ring of the bearing in the steered state. A rack and pinion type steering device characterized in that a sheet-like inclusion having a small friction coefficient is attached to the support yoke receiving surface.
