摘要： A rack guide device includes a rack guide, a blocking member, a plate spring and a holding member. The rack guide is accommodated in an accommodating portion that is formed in a housing through which a rack shaft is inserted so as to move towards or away from the rack shaft and that supports the rack shaft so that the rack shaft slides in an axial direction thereof. The blocking member is fixed to an external opening end provided on an opposite side of the accommodating portion to a side thereof that faces the rack shaft. The disc spring is interposed between the blocking member and the rack guide to bias the rack guide towards the rack shaft. The holding member holds the disc spring and is directly or indirectly held to the rack guide or the blocking member through frictional engagement.

摘要： A rack bush, which constitutes a rack and pinion type steering system and supports a rack shaft in which rack teeth are formed at one circumferential portion, includes a bush main body and a rigidity reducing portion. The bush main body has an annular shape into which the rack shaft is inserted. The bush main body is divided, in a circumferential direction, into two portions including a rack teeth-side portion located on the same side as the rack teeth in the circumferential direction and a back face-side portion other than the rack teeth-side portion. The rigidity reducing portion is provided in the rack teeth-side portion, and makes a rigidity of the rack teeth-side portion lower than a rigidity of the back face-side portion.
