PURPOSE: A rotation preventive apparatus of a steering shaft is provided to prevent a driver from being injured by restricting rotation of a steering column and displacement with inserting a fitting protrusion to a fitting hole of a fixing bracket. CONSTITUTION: A rotation preventive device of a steering shaft(20) is composed of a lower jacket(21) combined with the steering shaft by inserting a rotating member(22); a lower bracket(23) fixed in the lower part of the lower jacket; and a fixing bracket(24) combined with the lower bracket by a bolt, and fixed in a vehicle body. A rotation preventive sill(24a) is bent inward in the fixing bracket to prevent rotation of the lower bracket. A fitting protrusion is bent outward in the end of the lower bracket, and a fitting hole is formed in the fixing bracket. Impact is absorbed with bending the steering shaft and the lower jacket at a collision, and rotation of the lower jacket is restricted with fitting the lower bracket to the rotation preventive sill. The driver is protected against displacement or rotation of the lower jacket with inserting the fitting protrusion to the fitting hole.
