<P>PROBLEM TO BE SOLVED: To enable the operation of a steering wheel after a secondary collision by smoothly absorbing impact energy in the secondary collision by a simple and lightweight structure. <P>SOLUTION: Until an upper vehicle body installing bracket 21 moves by a collapse moving distance L1 and reaches a collapse moving end on the vehicle body front side, a flange 21a of the upper vehicle body installing bracket 21 is guided along vehicle body front side extension parts 243 and 243. Thus, the flange 21a of the upper vehicle body installing bracket 21 can move to the collapse moving end so as to be collapsible without falling off from capsules 24 and 24. Thus, owing to light weight and simple structure, an increase in manufacturing cost is restrained, and the impact energy in a collision is smoothly absorbed, and since the operation of the steering wheel 101 becomes possible even after the second collision, driving operation such as retreating to a safe place can be performed by maneuvering a vehicle. <P>COPYRIGHT: (C)2013,JPO&INPIT |
