The present invention discloses a vehicle steering system (100) having a rack bar supporting apparatus (130) which prevents the rotation of a rack bar (120) and makes the rack bar supporting apparatus (130) compact by providing a plurality of rack bar supporting apparatuses (170) installed at the rear of the rack bar (120) to support the rack bar (120) in the direction of a pinion gear (111). The vehicle steering system (100) comprises a pinion shaft (110) having a pinion gear (111) on the outer circumference and being installed within a housing (102); a rack bar (120) being located within the housing (102) so that it can cross the pinion shaft (110) and having a rack gear (121) meshing with the pinion gear (111) at one side of the middle part; and rack bar supporting apparatus (130) provided on the rear surface of the rack bar (120) for elastically supporting the rack bar (120) in the direction of the pinion shaft (110), wherein a plurality of the rack bar supporting apparatuses (170) are provided to vary the supporting direction and supporting force for supporting the rack bar (120). <IMAGE> |
