Abstract: A steering device includes a cylindrical inner column, a cylindrical outer column, a column bracket, a tilt bolt, a lock member attached to the outer periphery of the tilt bolt, a first fixing mechanism, and a second fixing mechanism. The first fixing mechanism clamps the outer column by a pressing bracket in response to the rotation of an operation lever. The second fixing mechanism urges the lock member to the inner column in the tilt direction in response to the rotation of the operation lever. When the inner column moves toward a front side of a vehicle body in a state where the first fixing mechanism and the second fixing mechanism are fixed, the lock member separates from the tilt bolt.
