A steering apparatus for a vehicle includes a stem pipe disposed in a head pipe by upper and lower bearings interposed therebetween, a seal member for covering the upper bearing, and bottom and top bridges mounted on lower and upper ends of the stem pipe, respectively. A single fastening bolt, having a step formed between a head and a threaded surface thereof, is fitted in a pipe insertion hole of the top bridge and the upper threaded portion of the stem pipe. The stem pipe is firmly tightened and supported by a stem pipe slot-tightening mechanism of the top bridge. The fastening bolt is tightened by only a tightening force required to keep the fastening bolt from loosening. Also, a number of components required for the inventive steering apparatus is reduced, since an additional component, previously used for preventing loosening of a fastening bolt, is made unnecessary.
