Abstract: A shock absorbing device for a steering column. The shock absorbing device is provided in the interferential fitting junction between the upper and lower columns of the steering column. The shock absorbing device has a plurality of friction members formed on the upper column by a piercing process, with the base part of each friction member facing the outside of the upper column and the remainder being folded down into the internal surface of the upper column to form a friction part. The friction part is brought into frictional contact with the external surface of the lower column, thus increasing the frictional contact surface area of the shock absorbing device. The shock absorbing device effectively absorbs and relieves shock in the initial stage of a car collision, thus effectively preventing the shock from being transmitted to a steering wheel in order to protect the driver in a collision.
