Abstract
A shock absorbing type steering device decreases variations in press fitting loads corresponding to a friction force between two columns. A shock can be appropriately absorbed by relative movements of the two columns in an axial direction. At least one of a first column and a second column press fitted into an opening at one end of the first column is formed with swaged parts on a peripheral wall thereof at a plurality of positions having intervals in a circumferential direction of the column, respectively at a plurality of positions having intervals in an axial direction of the column. Positions of tip ends of the swaged parts are different between a group of swaged parts near the opening at the end of the first column and other groups remote from the opening.
