In an impact-absorbing member which extends in a vehicle length direction of an automobile and whose both end portions in the vehicle length direction have a collision-side end portion and a non-collision-side end portion whose positions become mutually different when seen from the vehicle length direction, an outer member and an inner member of the impact-absorbing member are formed so that a position of a gravity center at the collision-side end portion and a position of a gravity center at the non-collision-side end portion become mutually different according to a positional relationship between the collision-side end portion and the non-collision-side end portion in order to suppress a tensile stress generated at the collision-side end portion and suppress a compressive stress generated at the non-collision-side end portion in a collision.

Impact-absorbing member and side member of automobile

[Object] To improve load resistance performance in response to collision. [Solution] An end structure of a vehicle according to the present invention includes: a beamthat extends in a vehicle width direction; and a connecting structurethat connects the beamto a vehicle body frame. In a cross-sectional view perpendicular to the vehicle width direction, the beamincludes a first top surface partand a first bottom surface partwhich face each other, a first side surface partthat connects one ends of the first top surface partand the first bottom surface part, and first flange partsthat are formed to protrude vertically outwardly at the other ends of the first top surface partand the first bottom surface part. The beamis fixed to the connecting structureby at least one of bonding of a protrusionthat is provided in the connecting structureand is arranged to protrude inside the beamto the first top surface partand the first bottom surface partand bonding of a beam attachment member provided in the connecting structureto the first flange parts
