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.

Abstract: The present invention provides a shock absorbing type steering device in which variations in press fitting loads corresponding to a friction force between two columns are decreased, whereby a shock can be appropriately absorbed by relative movements of the two columns in an axial direction. According to the shock absorbing type steering device, 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. And, positions of tip ends of said swaged parts are difference between a group of swaged parts near the opening at the end of said first column and other groups remote from the opening.

Abstract: A method of producing a reinforced rubber hose, including the steps of continuously extruding a long plastic mandrel from a plastic material and feeding the extruded plastic mandrel, extruding an unvulcanized inner rubber tube on the long plastic mandrel, forming a tubular reinforcing layer on the unvulcanized inner rubber tube, extruding an unvulcanized outer rubber tube on the tubular reinforcing layer, vulcanizing the unvulcanized rubber tubes, thereby preparing a long rubber hose formed on the long plastic mandrel, cutting the long rubber hose into short rubber hoses having a predetermined length, while concurrently cutting the long plastic mandrel into short plastic mandrels, removing the short plastic mandrels from the short rubber hoses, and crushing the short plastic mandrels into a starting form of the plastic material, and returning the starting form of the plastic material to an extruder for continuously extruding the long plastic mandrel.
