Abstract: A rack bush for supporting a rack shaft in a rack-and-pinion steering system so that the rack shaft slides in an axial direction thereof includes a teeth side support portion and a back side support portion. Rack teeth are formed in a first area of an outer circumferential surface of the rack shaft. The teeth side support portion contacts a second area of the outer circumferential surface to support the rack shaft from a teeth side where the rack teeth are formed. The second area lies adjacent to the first area in the axial direction. The back side support portion contacts a third area of the outer circumferential surface to support the rack shaft from a back side other than the teeth side. The third area is positioned out of the first area in a circumferential direction around an axis of the rack shaft.

Abstract: In a resin backlashless gear 1, the radial outer portions 7, 8 of first and second gear portions 3, 4 are connected to a radial inner portion 2 by means of radial ribs 10, 11 so as to be capable of being displaced in rotational directions. The elastic deformation of the radial ribs 10, 11 decreases the dislocation of the teeth 5, 6 of the first and second gear portions 3, 4 in pitch circle directions so that the dislocation is equal to backlash to cause the teeth 5, 6 of the first and second gear portions 3, 4 to elastically contact the teeth of a companion gear meshing with the resin gear to absorb the backlash.
