发明名称 Steering device
摘要 An impact absorbing device includes an impact absorbing plate provided integrally with the second column tube, the impact absorbing plate being configured to absorb the impact energy, and a pressing member provided integrally with the first column tube, the pressing member being configured to generate deformation resistance by pressing and deforming the impact absorbing plate. A guide hole extending in the axial direction of the steering shaft is formed on the impact absorbing plate, and a guide that relatively moves along the guide hole upon relative movement in the axial direction of the first column tube and the second column tube is provided integrally with the first column tube.
