1. A steering device comprising:
a column pipe; an outer housing having a clamping portion that slidably clamps the column pipe; a pair of stopper plates that face each other and are mounted on the column pipe at a predetermined interval in an axial direction thereof; a fastener having a bolt shaft that is mounted on the clamping portion so as to fasten the clamping portion to thereby fix the column pipe; and a buffer member, wherein the buffer member is mounted on any one of the pair of facing stopper plates and the bolt shaft and makes contact with the other by mutual displacement, a plurality of projection ribs formed in a prismatic shape having a triangular cross-sectional shape with two inclined surfaces are formed on a contacting surface of the buffer member in a zigzag form or in a triangular sawtooth form, wherein the plurality of projection ribs of the buffer member respectively have different amounts of protrusion.
