Steering wheel position adjustment device

A steering wheel position adjustment device in which a stopper shock-absorbing material for absorbing shocks during tilt/telescopic adjustment can be mounted on a predetermined position extremely easily and shock-absorbing capacity can be improved. The steering wheel position adjustment device comprises: a movable bracket (1) having adjusting long holes (13) on both sides in a width direction of the movable bracket (1); a fixed bracket (2); a lock shaft (5) penetrating through both of the adjusting long holes (13) to support the movable bracket (1) to the fixed bracket (2); a collar member (6) which is rotatably supported within the movable bracket (1) by the lock shaft (5) and is capable of moving along, with the lock shaft, in a longitudinal direction; and stopper shock-absorbing materials (8), which are attached to both side sections in the longitudinal direction of the adjusting long holes (13) within the movable bracket (1), and each of which is formed thereon with an abutment surface against which the collar member abuts. When each of the stopper shock-absorbing materials (8) and the collar member (6) abut against each other, both end portions in a width direction of the abutment surface of the stopper shock-absorbing material are first brought into abutment.
