Abstract
A shock absorbing type steering device for use in a motor vehicle, comprising a shaft adapted to transmit a torque from a steering wheel to a steering gear, which shaft consists of a first solid shaft portion and a second hollow or cylindrical shaft portion. The second cylindrical shaft portion includes a small diameter portion and a large diameter portion. Part of the first solid shaft portion is rigidly fitted in the aforesaid small diameter portion of the second cylindrical shaft portion with the aid of shear pins, while a shock-absorbing resilient material is contained in the aforesaid large diameter portion of the second cylindrical shaft portion. The shock absorbing material is of such a property that it is ruptured due to stresses exceeding a given level. A passage leading from the interior of the aforesaid large diameter portion of the second cylindrical shaft portion to atmosphere runs either through the first solid shaft portion or through the second cylindrical shaft portion.
