Provided is a collision energy absorbing apparatus capable of mitigating loads to the car body proper, passengers and the like by adding a structure combining a prescribed static strength and collision energy absorption performance to an energy absorbing body of the collision energy absorbing apparatus. In a limited inner space of a car body, a cover 80 that covers energy absorbing bodies 51, 52 combines a prescribed static strength and collision energy absorption performance.
