摘要： PROBLEM TO BE SOLVED: To provide a method for absorbing impact energy capable of stably generating plastic buckling deformation when an impact load acts in the axial direction even in a long impact absorbing member for a vehicle.
SOLUTION: The impact absorbing member has a cylindrical body having a groove at least in a part of the axial direction which has a flat approximately polygonal transverse cross sectional shape, is projected toward inside on a wide width surface including the long side of the flat approximately polygonal shape and extends to the direction approximately parallel to the axial direction. The impact absorbing member is mounted to a predetermined position of the vehicle body, and the body is buckled and deformed in an accordion shape at a collision time of the vehicle body to absorb the impact energy. The groove effectively absorbs the impact energy of the vehicle body by satisfying Dy/Dz≥1.0 at the time of buckling deformation in a bellows shape. Dy is the displacement to the Y direction of the bottom of the groove, Dz is the displacement to the Z direction of the bottom of the groove, the Y direction is a direction orthogonal to the depth direction of the groove on the surface orthogonal to the axial direction of the body, and the Z direction is the depth direction of the groove on the surface orthogonal to the axial direction of the body.
