PROBLEM TO BE SOLVED: To sufficiently and appropriately absorb the impact energy at the time of collision of a vehicle, and to securely prevent the apply of an excessive load to a driver by using a spacer made of the synthetic resin in an impact absorption type steering column. SOLUTION: A cylindrical second column 2b is pressed into a cylindrical first column 2a through a spacer 3. As a material of the spacer 3, the ultrahigh molecular weight polyethylene at 500,000-6,000,000, desirably at 3,000,000-4,500,000 of molecular weight is used. |
