ABSTRACT:
An energy absorbing structure for a side portion of a vehicle body includes a plastically deformable energy absorbing member which is disposed at a predetermined position in the side portion of the vehicle body against which a side portion of an upper part of a vehicle occupant's body hits during a side collision, the energy absorbing member being arranged such that a longitudinal direction thereof coincides with a longitudinal direction of the vehicle body, a cross section of the energy absorbing member being formed in the shape of a substantially hollow ellipse in which a direction of a short axis thereof is a transverse direction of the vehicle body and a direction of a long axis thereof is a vertical direction of the vehicle body, the wall thickness of the energy absorbing member being set such that the wall thicknesses of long-axis portions thereof corresponding to the long axis are greater than the wall thicknesses of short-axis portions thereof corresponding to the short axis.
