Abstract
A steering shock absorbing apparatus for motor vehicle according to the invention comprises a first universal joint for interconnecting a first end of an intermediate shaft and a steering shaft, and a second universal joint for interconnecting a second end of the intermediate shaft and an input shaft of a steering gear. The intermediate shaft includes a hollow bellows portion having slant convexes and slant concaves alternating with each other. A line interconnecting the joint centers of the first and second universal joints is tilted to the center axis of the intermediate shaft at a predetermined angle. At motor vehicle collision, a bending moment derived from an impact force of the collision is exerted on the intermediate shaft because the line is tilted. As a result, the intermediate shaft is bucklingly contracted at the bellows portion thereof.
