A steering system comprising: a column jacket pivotable in a tilt direction, the column jacket including a pair of facing portions protruding from an outer peripheral portion of the column jacket and facing each other, and a stepped portion which extends in an intersecting direction with respect to an axial direction of the column jacket and at which an outer surface of a corresponding one of the facing portions projects outward halfway from a first end side to a second end side of the column jacket in the axial direction; a bracket fixed to a vehicle body, the bracket including a pair of side plates disposed on outer sides of the respective facing portions and extending to the first end side to intersect with the tilt direction, and tilt grooves formed in the respective side plates and extending in the tilt direction; and a clamping mechanism that clamps the side plates to bend the side plates such that an end of each of the side plates on the first end side is displaced toward a corresponding one of the facing portions, the clamping mechanism including a clamping shaft that is inserted through the tilt grooves to move in the tilt direction in the tilt grooves when the column jacket pivots in the tilt direction; characterized in that the stepped portion is located between a portion serving as a fulcrum when a corresponding one of the side plates is bent by being clamped by the clamping mechanism and a corresponding one of the tilt grooves, in a direction in which the side plates extend. a column jacket pivotable in a tilt direction, the column jacket including a pair of facing portions protruding from an outer peripheral portion of the column jacket and facing each other, and a stepped portion which extends in an intersecting direction with respect to an axial direction of the column jacket and at which an outer surface of a corresponding one of the facing portions projects outward halfway from a first end side to a second end side of the column jacket in the axial direction; a pair of facing portions protruding from an outer peripheral portion of the column jacket and facing each other, and a stepped portion which extends in an intersecting direction with respect to an axial direction of the column jacket and at which an outer surface of a corresponding one of the facing portions projects outward halfway from a first end side to a second end side of the column jacket in the axial direction; a bracket fixed to a vehicle body, the bracket including a pair of side plates disposed on outer sides of the respective facing portions and extending to the first end side to intersect with the tilt direction, and tilt grooves formed in the respective side plates and extending in the tilt direction; and a pair of side plates disposed on outer sides of the respective facing portions and extending to the first end side to intersect with the tilt direction, and tilt grooves formed in the respective side plates and extending in the tilt direction; and a clamping mechanism that clamps the side plates to bend the side plates such that an end of each of the side plates on the first end side is displaced toward a corresponding one of the facing portions, the clamping mechanism including a clamping shaft that is inserted through the tilt grooves to move in the tilt direction in the tilt grooves when the column jacket pivots in the tilt direction; characterized in that the stepped portion is located between a portion serving as a fulcrum when a corresponding one of the side plates is bent by being clamped by the clamping mechanism and a corresponding one of the tilt grooves, in a direction in which the side plates extend.
