Abstract

PURPOSE:To protect a driver from the secondary shock in collision by a method wherein the secondary collision energy, which is applied just after the application of the primary collision energy, causes the steering shaft to be smoothly movable downward. CONSTITUTION:The steering shaft 5 consists of an upper shaft 7 and a lower shaft 8, in the tubular part of which the upper shaft 7 is fitted and coupled with the lower shaft 8 by a spline joint. A ball groove 7a and a deep groove 20, into which steel balls 14 are able to be fallen down, are formed on the outer periphery of the shaft 7. The shafts 7 and 8 are made into one body by fitting the steel balls 14 in said groove 7a. Because the balls 14 held between the shafts 7 and 8 are caused to be fallen down into the deep groove 20 by means of the primary collision energy, the shaft 7 can be pushed into the shaft 8 smootly by applying light force at the secondary collision.
