PROBLEM TO BE SOLVED: To provide an impact absorbing structure which can stably absorb an impact at a vehicle collision and a steering device including the impact absorbing structure.SOLUTION: An impact absorbing structure 70 used in a steering device 1 includes: a first fixed part 73 fixed to an upper jacket 22 which is movable to axial direction X; a second fixed part 74 which is brought into a fixed state to a vehicle body side when a vehicle collision occurs; and a groove 87 which extends along the axial direction X between the first fixed part 73 and the second fixed part 74, and whose front end 87A is opened to a front side X2. An inclined part in which the groove 87 is gradually deepened as progressing toward the front side X2 is arranged at the front end 87A. At a vehicle collision, the first fixed part 73 which moves integrally with the upper jacket 22 relatively moves to the second fixed part 74, the first fixed part 73 and the second fixed part 74 are torn from each other by the groove 87 with the front end 87A as a starting point.SELECTED DRAWING: Figure 4

    【課題】車両衝突時の衝撃を安定して吸収できる衝撃吸収構造および当該衝撃吸収構造を含むステアリング装置を提供すること。【解決手段】ステアリング装置1に用いられる衝撃吸収構造70は、軸方向Xに移動可能なアッパージャケット22に固定される第1固定部73と、車両衝突時には車体側に固定された状態にある第2固定部74と、第1固定部73と第2固定部74との間で軸方向Xに沿って延び、前端部87Aが前側X2へ開放された溝87とを含む。前端部87Aには、前側X2へ向かうにつれて溝87を次第に深くする傾斜部が設けられている。車両衝突時には、アッパージャケット22と一体移動する第1固定部73が第2固定部74に対して相対移動することによって、第1固定部73と第2固定部74との間が、前端部87Aを起点として溝87に沿って引き裂かれる。【選択図】図4
