PURPOSE: Assembling structure of a rack bush for a steering system in a vehicle is provided to reduce noise, and to prevent deformation by filling a slot of a rack bush and a gap between the rack bush and a stopper. CONSTITUTION: A rack bush assembling system of a steering system for a vehicle is composed of a rack housing(2) having an opening part(21) in the outer periphery; a rack bush(3) inserted to the rack housing; a rack bar inserted to the rack bush to move axially; a rack stopper(4) installed in the outer periphery of the rack bar to close the end of the rack housing; and an insertion member(5) filled between the rack stopper and the rack bush. A protrusion part(33) of the rack bush is inserted to the opening part of the rack housing, and a slot part(32) is extended and cut in the rack bush. Noise is reduced, and torsion deformation is prevented with filling the slot part of the rack bush and clearance between the rack bush and the stopper.
