ABSTRACT:
In order to obtain sufficient energy absorbing capacity and, at the same time, to reduce the number of components and simplify assembly, synthetic resin is disposed between a shaft and a tube. The synthetic resin is torn and broken when strong compressive force in the axial direction is given at the time of a car crash, allowing the shaft to be pushed deeply into the tube until it contacts a pin. In this state, the contact position between one end of the tube and a cover tube substantially coincides with a small-cross-section portion formed in an intermediate part of the shaft. As a result, the shaft can bend at the small-cross-section portion.
