PROBLEM TO BE SOLVED: To provide a steering system including a member susceptible of rupturing that ruptures upon receiving an impact and capable of preventing rupture of the member caused by an impact applied during telescopic adjustment.SOLUTION: A second toothed member 50 is configured to change its position between a meshing position where first teeth 41 mesh with second teeth 51 and a meshing releasing position where the first teeth 41 do not mesh with the second teeth 51. A first toothed member 40 and a facing member 81 move together with an upper jacket 7. The second toothed member 50 located at the meshing position receives an impact from the first toothed member 40 so as to collide against an impact absorbing member 110 after rupture of a guide shaft 61 and deform the impact absorbing member 110. The second toothed member 50 located at the meshing releasing position receives an impact from the facing member 81 so as to cause rupture of the guide shaft 61 and deformation of the impact absorbing member 110 to occur concurrently.SELECTED DRAWING: Figure 7 【課題】衝撃を受けて破断する破断部材を含む構成において、テレスコ調整時の衝撃による破断部材の破断を抑制することができるステアリング装置を提供する。【解決手段】第２ツース部材５０は、第１ツース４１と第２ツース５１とが噛み合う噛合位置と、第１ツース４１と第２ツース５１との噛合が解除された噛合解除位置との間で変位可能である。第１ツース部材４０と対向部材８１とが、アッパジャケット７と一体移動する。第２ツース部材５０は、噛合位置に位置する状態で第１ツース部材４０から衝撃を受けることによって、案内軸６１が破断した後に衝撃吸収部材１１０に衝突し衝撃吸収部材１１０を変形させる。第２ツース部材５０は、噛合解除位置に位置する状態で対向部材８１から衝撃を受けることによって、案内軸６１の破断と衝撃吸収部材１１０の変形とを並行して起こさせる。【選択図】図７
