Patent attributes
In a tilt and/or telescopic type steering column apparatus for a vehicle, in which a column sided bracket attached to a steering column is so provided as to be swingable and/or slidable on a car body sided bracket attached to a car body, a fastening bolt is inserted through a tilt adjustment hole formed in the car body sided bracket and through a telescopic adjustment hole formed in the column sided bracket, the two brackets are pressure-contacted to each other by fastening the fastening bolt and thus fastened in a tilt and/or telescopic adjustment position, while a tilt and/or telescopic adjustment can be made by releasing the two brackets from being pressure-contacted by slackening the fastening bolt, and each of the tilt adjustment hole and the telescopic adjustment hole has a slight gap with respect to the fastening bolt, a steering column apparatus for a vehicle is constructed such that an annular or cylindrical elastic member for preventing a backlash of the fastening bolt from being caused corresponding to the slight gap when making the tilt and/or telescopic adjustment, is fitted on an outer peripheral surface of the fastening bolt.
