A steering device includes a cylindrical inner column that supports an input shaft connected to a steering wheel so as to allow the input shaft to be rotatable, a cylindrical outer column into which at least a part of the inner column is inserted, and a cylindrical lower column that supports an output shaft connected to the input shaft so as to allow the output shaft to be rotatable and is supported by a dash panel. The lower column moves to a rear side at the time of a primary collision, and the inner column and the outer column move relative to each other at the time of a secondary collision.
