Beschreibung
Zusammenfassung:	A steering apparatus includes: a column shaft (110); a column tube (120) supporting the column shaft; a housing (130) movably supporting the column tube; a fastener (140) configured to fix the position of the column tube by pressing on radial ends of the housing; a first impact absorber (150) configured to generate a first dynamic friction force with the column tube; and a second impact absorber (160) 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 (152) located further from a squeezing portion of the fastener is less than a proximal static friction coefficient in a proximal region (151) closer to the squeezing portion.
