Long hole portions that extend in the axial direction and are each formed of a telescopic long hole and a shock absorbing long hole are formed in the first suspended plate-like portion and the second suspended plate-like portion respectively. A telescopic stopper is provided in at least either one of the long hole portions. An inclined region including a plurality of consecutive inclined sides and the vertical size of which gradually becomes narrow is provided in the other long hole portion. ## Claims ### Claim 1 A steering device, comprising: a column pipe; a hanger bracket having a first suspended plate portion and a second suspended plate portion and fixed firmly to the column pipe; an outer column having an enclosing main body portion enclosing the column pipe and a tightening portion; a fixed bracket supporting the outer column; and a tightening tool that tightens and loosens the outer column and the fixed bracket and has a bolt shaft collapsing a telescopic stopper at a time of a secondary collision, wherein long hole portions that extend in an axial direction and are each formed of a telescopic long hole and a shock absorbing long hole are formed in the first suspended plate portion and the second suspended plate portion respectively, the telescopic stopper is provided in one of the long hole portions, an inclined region which is formed of a plurality of consecutive inclined sides and a vertical size of which gradually becomes narrow is provided in the other long hole portion, and a starting point of the inclined region is located at the front side with respect to the telescopic stopper. ### Claim 2 (depends on 1) The steering device according to claim 1, wherein the inclined region has a first inclined side and a second inclined side located at the rear side with respect to the first inclined side, the first inclined side having an inclination angle larger than that of the second inclined side. ### Claim 3 (depends on 2) The steering device according to claim 2, wherein the inclined regions are formed in the first suspended plate portion and the second suspended plate portion respectively. ### Claim 4 (depends on 1) The steering device according to claim 1, wherein the inclined region has a first inclined side and a second inclined side located at the rear side with respect to the first inclined side, the second inclined side having an inclination angle larger than that of the first inclined side. ### Claim 5 (depends on 1) The steering device according to claim 1, wherein the inclined region has a first inclined side, a second inclined side located at the rear side with respect to the first inclined side, and a third inclined side located at the rear side with respect to the second inclined side, the first inclined side, the second inclined side, and the third inclined side having angles different from one another. ### Claim 6 (depends on 5) The steering device according to claim 5, wherein the second inclined side has the largest angle and the third inclined side is set to have the smallest angle. ### Claim 7 (depends on 1) The steering device according to claim 1, wherein the inclined regions are formed in the first suspended plate portion and the second suspended plate portion respectively.
