摘要:
A telescopic steering column device comprising: a drive-side steering shaft; a driven-side steering shaft; a cylindrical inner column having an elongated hole in the axial direction; a cylindrical outer column having an opening corresponding the elongated hole in the inner column, fastened on the outer surface of the inner column so as to be telescopically combined with the inner column; a lock bracket having a thread hole corresponding the opening in the outer column; a lock member having a through hole at the central portion, the lock member being arranged to be fitted within the opening; and a lock screw having the inner portion which is engaged with the lock member and a projection which is formed at the central portion of the inner portion, which is rotatably inserted into the through hole of the lock member and which is inserted into the elongated hole in the inner column so that the axial displacement of the inner column with respect to the outer column is allowed while the rotation of the inner column with respect to the outer column is prevented, the lock screw being driven into the thread hole in the lock bracket, whereby the inner column is secured to the outer column by abutting the inner surface of the lock member against the outer surface of the inner column by adjusting the lock screw, and the inner column can be expanded/contracted by releasing the abutment.
