Abstract: A second toothed member is configured to change its position between a meshing position where first teeth mesh with second teeth and a meshing releasing position where the first teeth do not mesh with the second teeth. A first toothed member and a facing member move together with an upper jacket. The second toothed member located at the meshing position receives an impact from the first toothed member so as to collide against an impact absorbing member after rupture of a guide shaft and deform the impact absorbing member. The second toothed member located at the meshing releasing position receives an impact from the facing member so as to cause rupture of the guide shaft and deformation of the impact absorbing member to occur concurrently.

Abstract: A rack bushing supported by an annular elastic member in a housing includes a bushing body and a flange portion extending outward in a radial direction from a first axial end of the rack bushing. The flange portion is positioned at a step portion of an inner periphery of the housing. The bushing body includes a second axial slit extending from a second axial end to a middle portion in an axial direction. A gap that communicates with the second axial slit is formed between the inner periphery of the housing and an outer surface of the bushing body. A recessed groove (communication passage) of the flange portion allows a first space, disposed on a housing-end side with respect to the rack bushing in the housing, to communicate with the gap.
