Steering system

A steering system comprising:

• a steering member;
• a steering shaft to which the steering member is coupled at one end of the steering shaft and which is configured to extend and contact in an axial direction;
• a column jacket having an inner jacket in which an insertion hole extending in the axial direction is provided in an outer surface of the inner jacket and which supports the steering shaft, and an outer jacket that houses the inner jacket to support the steering shaft, the column jacket configured to extend and contract in the axial direction along with the steering shaft as a result of relative movement between the inner jacket and the outer jacket in the axial direction;
• a regulation member that is fixed to the outer jacket and passes through the insertion hole and that regulates a distance of the relative movement between the inner jacket and the outer jacket to within a range in which the regulation member is allowed to move in the axial direction within the insertion hole, the regulation member allowed to be sheared;
• and
• an elastic member that has a tip portion arranged on the outer surface of the inner jacket at a position away from the insertion hole in the axial direction and that is fixed to the outer jacket, wherein
• when, at a time of vehicular collision, the regulation member is sheared by a peripheral portion of the insertion hole in the inner jacket in conjunction with the relative movement between the inner jacket and the outer jacket, the elastic member is elastically deformed so that the tip portion is fitted in the insertion hole.
