A rack guide device comprising: a rack guide that is accommodated in an accommodating portion formed in a housing through which a rack shaft configured to mesh with a pinion shaft is inserted so as to move towards and away from the rack shaft and that supports the rack shaft so that the rack shaft slides in an axial direction of the rack shaft; a blocking member that is fixed to an external opening end that is provided on an opposite side of the accommodating portion to a side thereof that faces the rack shaft; and at least one disc spring that is interposed between the blocking member and the rack guide to bias the rack guide towards the rack shaft; wherein a recess portion is provided on the blocking member, and the rack guide device further comprises a holding member that holds the disc spring and that includes a guide tube that guides a radial end portion of the disc spring, wherein an outer circumference of the guide tube is directly or indirectly held through frictional engagement to an opposing portion as an inner circumference of the recess portion; characterized by the holding member comprising an annular washer plate that extends radially from a first end portion being an axial end of the guide tube to receive a load of the disc spring; wherein a gap is provided between a second end portion of the guide tube opposite the first end portion and a bottom of the recess portion, in relation to a direction in which the rack guide moves towards or away from the rack shaft, the gap being equal to or greater than a distance over which the rack guide moves towards or away from the rack shaft; the rack guide device comprises a frictional engaging member (23, 41) including an elastic member (23, 41) that is held on at least one of the blocking member and the holding member and is in frictional engagement with the other, and the frictional engaging member is interposed between the circumferential surface of the guide tube and the opposing portion of the blocking member. a rack guide that is accommodated in an accommodating portion formed in a housing through which a rack shaft configured to mesh with a pinion shaft is inserted so as to move towards and away from the rack shaft and that supports the rack shaft so that the rack shaft slides in an axial direction of the rack shaft; a blocking member that is fixed to an external opening end that is provided on an opposite side of the accommodating portion to a side thereof that faces the rack shaft; and at least one disc spring that is interposed between the blocking member and the rack guide to bias the rack guide towards the rack shaft; wherein a recess portion is provided on the blocking member, and the rack guide device further comprises a holding member that holds the disc spring and that includes a guide tube that guides a radial end portion of the disc spring, wherein an outer circumference of the guide tube is directly or indirectly held through frictional engagement to an opposing portion as an inner circumference of the recess portion; characterized by the holding member comprising an annular washer plate that extends radially from a first end portion being an axial end of the guide tube to receive a load of the disc spring; wherein a gap is provided between a second end portion of the guide tube opposite the first end portion and a bottom of the recess portion, in relation to a direction in which the rack guide moves towards or away from the rack shaft, the gap being equal to or greater than a distance over which the rack guide moves towards or away from the rack shaft; the rack guide device comprises a frictional engaging member (23, 41) including an elastic member (23, 41) that is held on at least one of the blocking member and the holding member and is in frictional engagement with the other, and the frictional engaging member is interposed between the circumferential surface of the guide tube and the opposing portion of the blocking member.
