as the mayor of automobile steering column impact absorption structure

摘要

The present invention relates to a steering column impact-absorbing structure of the steering system by the bowl type, more specifically the steering column impact-absorbing structure of the vehicle steering apparatus to effectively absorb the impact force as the driver's body, a bump on the handle It relates.; The present invention is an upper column tube 100 and the lower column tube 200 is fitted coaxially, and the upper column tube 100 and the lower column tube of a plurality of steel ball-support to the cage made of resin between 200 300 a in the steering column impact-absorbing structure of the vehicle steering device by press-fitting, expanding the diameter of the overlapping portion (A1, A2) of one of said upper column tube 100 and the lower column tube (200) or by shrinking, and that is characterized in that a surface contact to occur when the upper column tube 100 and the lower column tube 200 is compressed.
