The energy absorbing steering assembly of this invention has a steering shaft collapsible as a vehicle impacts an obstacle, and the steering shaft consists of an upper and lower shafts, and the upper portion of the lower shaft and the lower portion of the upper shaft fit with each other. A spherical projection is provided on the surface of an unfitted portion of one of said shafts spaced a given distance from the end surface of the fitted portion, said one shaft being fitted into the inside of the other shaft. When the steering shaft is collapsed, said spherical projection of the one shaft enters into the inner surface of the other shaft so as to produce a plastic deformation on this inner surface to absorb the impact energy.
