To provide a shock absorbing device capable of minimizing a peak load during a collision and reducing an impact force (acceleration) applied on a passenger and a crew on board by starting and promoting the crushing of energy absorbers immediately after the collision occurs when the energy absorbers receive compressive loads and experience elastic deformation.

A railway vehicle is equipped with a shock absorbing device 100 including an energy absorber 120 that absorbs collision energy by being crushed at the collision. The energy absorber 120 includes a tip L1 keeping a cross-sectional area orthogonal to the longitudinal direction reduced toward the tip, and a body L2 having a constant cross-sectional area connected between the tip L1 and a base end. During the collision, the crushing of the energy absorber 120 is started and promoted via a small load while the tip L1 is deformed within an elastic deformation zone, so that the peak load (acceleration) can be minimized.
