摘要： There is provided a steering system that can absorb an increased total amount of shock at a time of a secondary collision and that allows setting an appropriate shock load. A steering member (2) is connected to one end of an upper jacket (7) in a column axial direction (X). A lower jacket (8) is externally fitted with the other end of the upper jacket (7) in the column axial direction (X) so as to be slidable with respect to the upper jacket (7). The lower jacket (8) is supported by a support member (17) fixed to a vehicle body (13). At the time of a secondary collision, a first sliding member (40) generates a first resistive force by performing first relative sliding with respect to the upper jacket (7), and a second sliding member (50) which is moved together with the first sliding member (40) in the column axial direction (X) generates a second resistive force by performing second relative sliding with respect to the support member (17) and the lower jacket (8).
