To provide a collision energy absorption device for a vehicle which absorbs a large amount of collision energy and can further stabilize an impact absorption mode.SOLUTION: A collision energy absorption device (10) for a vehicle comprises: an energy absorption member (20); and a shell body (30). The shell body (30) includes a lower shell (31) and an upper shell (40). The energy absorption member (20) includes: a first energy absorption member (26); and a second energy absorption member (27) disposed adjacent to the first energy absorption member. In the shell body (30), a protruding part (46) or a recessed part which is set as a starting point of deformation is formed at the input side.SELECTED DRAWING: Figure 12
