A steering apparatus includes: a column shaft; a column tube supporting the column shaft; a housing movably supporting the column tube; a fastener configured to fix the position of the column tube by pressing on radial ends of the housing; a first impact absorber configured to generate a first dynamic friction force with the column tube; and a second impact absorber configured to generate a second dynamic friction force with the housing during a secondary collision by being moved by the first impact absorber. The first impact absorber is structured such that a distal static friction coefficient in a distal region located further from a squeezing portion of the fastener is less than a proximal static friction coefficient in a proximal region closer to the squeezing portion.

Steering apparatus

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.
