The apparatus prevents the shimmy phenomenon caused by a hydraulic pressure continuously increased on a full left steering or right steering. The apparatus comprises a spline shaft(11), rotating with a steering column and having a longitudinal spline; a lower fixture(15), combined with the spline of the shaft(11) and having a circumferential screw(16) and a stopper(20); a variable member(18), screwed with the screw(16) of the lower fixture(15) and having a plurality of guide protrusions(24) and an upward/downward protrusion(22,23); an upper fixture(19), combined with the spline of the lower fixture(15); a housing(10) having a guide groove(25) for making the guide protrusions inserted into.
