In a steering device, when a telescopic position of a steering wheel is disposed at a vicinity of an adjustment end on a front side of a vehicle body, if a large force is applied erroneously to the steering wheel toward the front side of the vehicle body, rear ends of telescopic position adjusting long grooves are brought into contact with a fastening rod and push the fastening rod to the front side of the vehicle body. An engaging protrusion pushes an inner column to the front side of the vehicle body. A large force to the front side of the vehicle body, which is applied to the steering wheel is supported by the vehicle body via the inner column, and a force which is applied to a vehicle body attaching bracket can be reduced. This prevents the vehicle body attaching bracket from becoming detached from the vehicle body.
