ABSTRACT:
An upper supporting member for supporting an upper pin projecting upwardly from a steering gear box is supported on a rear subframe extending in back of the steering gear box. A lower supporting member for supporting a lower pin projecting downwardly from the steering gear box is supported on a front subframe extending between the lower supporting member and a rear surface of an engine in front of the steering gear box. An upper end of a pinion shaft extending upwardly from the steering gear box and a lower end of a steering shaft are interconnected by an intermediate shaft which is capable of being broken by a shear pin. Upon collision of the vehicle, the steering gear box can be turned or rotated forwardly relative to the supporting structure, whereby the steering wheel can be reliably moved forwardly, or released from the steering gear box to provide a secondary stroke.
