There is provided a steering system that can absorb an increased total amount of shock at a time of a secondary collision. A steering member is connected to one end of an upper jacket in a column axial direction. A lower jacket is externally fitted with the other end of the upper jacket in the column axial direction so as to be slidable with respect to the upper jacket. The lower jacket is supported by a support member fixed to a vehicle body. At the time of a secondary collision, a first sliding member generates a first resistive force by performing first relative sliding with respect to the upper jacket, and a second sliding member which is moved together with the first sliding member in the column axial direction generates a second resistive force by performing second relative sliding with respect to the support member and the lower jacket.

Steering system

A steering apparatus includes an engaging portion movable in a predetermined moving direction at a time of a secondary collision; a fixation portion fixed to a vehicle body; and an absorbing member. The absorbing member includes a fixed portion fixed to the fixation portion, an engaged portion facing the engaging portion, and a connecting portion that includes a curved portion and connects the fixed portion and the engaged portion. An area of a cross-section of the curved portion taken along a plane perpendicular to a creeping direction along the curved portion varies depending on a position in the creeping direction. The connecting portion of the absorbing member is deformed so that the absorbing member absorbs energy of the secondary collision.
