It includes a yoke body installed in a housing of a steering gear box to support a rack bar; an elastic member to press the yoke body toward the rack bar; a press portion contacted with the elastic member to support the elastic member; and a yoke plug portion fixed to the housing to adjust the strength of supporting the elastic member by the press portion. ## Claims ### Claim 1 A yoke clearance compensator comprising: a yoke body having a cavity and configured to support a rack bar; a plate spring comprising a first main surface and a second main surface; and a pusher assembly comprising a pusher, a yoke plug and a torsion spring placed inside a bore of the yoke plug, wherein the torsion spring is connected to the pusher and configured to cause the pusher to rotate about an axis relative to the yoke plug, wherein the pusher is engaged with the yoke plug such that the pusher moves along the axis relative to the yoke plug as it rotates about the axis, the pusher comprising a convex portion, wherein the yoke body, the plate spring and the pusher assembly are arranged in order along the axis such: that the plate spring is interposed between the yoke body and the pusher assembly, that the cavity of the yoke body, a central portion of the plate spring and the convex portion of the pusher are aligned along the axis, that the first main surface of the plate spring faces the yoke body, that a perimeter of the plate spring on the first main surface abuts the yoke body, that the second main surface of the plate spring contacts the convex portion of the pusher, wherein the yoke clearance compensator is configured such that the torsion spring causes the pusher to rotate about the axis relative to the yoke plug and to move toward the yoke body along the axis, which causes the convex portion of the pusher to push the central portion of the plate spring such that the central portion of the plate spring is depressed toward the cavity of the yoke body and the perimeter of the plate spring exerts force to the yoke body along the axis for the yoke body to transmit the force to the rack bar. ### Claim 2 (depends on 1) The compensator of claim 1, wherein the yoke body comprises a recessed portion which is configured to receive the plate spring. ### Claim 3 (depends on 1) The compensator of claim 1, wherein the pusher comprises male threads, wherein the yoke plug comprises female threads which are configured to engage with the male threads such that the pusher is rotatably coupled to the yoke plug by engagement of the male and female threads. ### Claim 4 (depends on 1) The compensator of claim 1, further comprising a torsion adjustment member rotatably coupled to the yoke plug, wherein the torsion spring is interposed between the pusher and the torsion adjustment member, wherein one end of the torsion spring is connected to the torsion adjustment member and the torsion adjust member is rotatably engaged with the yoke plug such that rotation of the torsion adjustment member relative to the yoke plug causes torsion of the torsion spring to change. ### Claim 5 (depends on 4) The compensator of claim 4, wherein the plug yoke comprises a hole which comprises a tapered wall portion, and wherein the torsion adjustment member comprises a tapered body portion configured to fit the tapered wall portion. ### Claim 6 (depends on 4) The compensator of claim 4 further comprising a body fixing member configured to fix the torsion adjustment member to the yoke plug for preventing the torsion adjustment member from rotating relative to the yoke plug. ### Claim 7 (depends on 6) The compensator of claim 6, wherein the body fixing member is inserted into a hole of the yoke plug and configured to push the torsion adjustment member to the yoke plug. ### Claim 8 (depends on 7) The compensator of claim 7, wherein the body fixing member includes a metal material and is a shape of a pin. ### Claim 9 (depends on 1) The compensator of claim 1, further comprising a fixing member comprising a bar extending through a hole of the yoke plug and a hole of the pusher such that the fixing member inhibits the pusher from rotating relative to the yoke plug. ### Claim 10 (depends on 9) The compensator of claim 9, wherein the bar of the fixing member further extends toward outside the yoke plug.
