Provided is a steering apparatus that reduces variations in impact absorbing load caused by differences in a telescopic adjustment position. A second sliding member (50) includes a fixed portion (51)fixed to the first sliding member (40), and an extension portion (52) that extends in a column axis direction (X) and that has a coupled portion (52P) coupled to the fixed portion (51) at a predetermined location in the column axis direction (X). The second sliding member (50) being clamped by the clamping mechanism (18) slides relative to a supporting member (17) and a lower jacket (8) during a secondary impact. The second sliding member (50) includes a slit (54) that reduces coupling stiffness between the fixed portion (51) and the coupled portion of the extension portion so as to facilitate, in a clamping state of the clamping mechanism, deflection of the coupled portion of the extension portion relative to the fixed portion (51) in a lateral direction as seen from the column axis direction.
