Title:
SHOCK ABSORBER AND BUMPER DEVICE FOR VEHICLE
Document Type and Number:
Japanese Patent JP2011105109
Kind Code:
A
Abstract:
To provide a shock absorber and a bumper device for a vehicle, capable of further efficiently absorbing impact energy, by further stabilizing turning deformation.
A crash box 13 has a cylindrical small diameter part 21 and a cylindrical large diameter part 23 connected to the small diameter part 21 by expansively opening via an annular step height part 22, and absorbs the impact energy by absorbing an applied load by plastic deformation of folding back the small diameter part 21 in the large diameter part 23 with the annular step height part 22 as a starting point. The large diameter part 23 is provided with a projection part 26 projecting outside in the radial direction by extending in the axial direction.
