Abstract
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.
