<p>A steering shock absorbing apparatus for motor vehicle according to the invention comprises a first universal joint for interconnecting a first end (25) of an intermediate shaft (5) and a steering shaft (3), and a second universal joint (6) for interconnecting a second end (30) of the intermediate shaft (5) and an input shaft (8) of a steering gear. The intermediate shaft (5) includes a hollow bellows portion (52) having slant convexes (53) and slant concaves (54) alternating with each other. A line (D) interconnecting the joint centers (A1,A2) of the first and second universal joints (4,6) is tilted to the center axis (B1) of the intermediate shaft (5) at a predetermined angle (²). At motor vehicle collision, a bending moment derived from an impact force of the collision is exerted on the intermediate shaft (5) because the line (D) is tilted. As a result, the intermediate shaft (5) is bucklingly contracted at the bellows portion (52) thereof.</p> |
