Abstract
An energy absorber includes an external unit, a collision unit and a buffer unit. The external unit extends with forming a stepped portion, and forms a predetermined inner space. The collision unit extends from the inner space to outside, and moves toward the inner space due to an external impact. The buffer unit is disposed in the inner space, and is connected to the collision unit to absorb the external impact. The external unit cuts or performs cutting and absorbs the external impact, as the collision unit moves.
