STEERING SYSTEM

A column jacket includes a hollow outer jacket having a pair of clamped portions disposed to sandwich a slit between the clamped portions and a tubular inner jacket having, in an area where the inner jacket is fitted in the outer jacket, an elongated hole extending in an axial direction. A clamping mechanism clamps the pair of clamped portions with a pair of side plates of a fixed bracket. The elongated hole is disposed on any one of a first side and a second side, in the lateral direction, of a vertical plane passing through a central axis of the inner jacket, at a position other than on a straight line that extends in a vertical direction through the central axis.
