PURPOSE: To provide a low-cost and effective crash energy absorbing device for a vehicle steering device. CONSTITUTION: This vehicle crash energy absorbing device is incorporated in a steering column structure mountable to a breakaway mounting device, including an inner steering shaft 15 drivably coupled by a splined device 8 to an outer shaft 16. The inner shaft 15 has an energy absorbing member in the form of a tube 17 surrounding a pin mounted diametrically through the inner shaft 15. A crash induced force on the column structure causes the outer shaft 16 to be forced relatively towards the tube 17, thereby inducing an interaction between the pin and the tube 17, the tube 17 being deformed thereby to achieve requisite energy absorption. |
