摘要： A main body of an impact energy absorber is formed by integrally molding a deformable portion and a plurality of deformation controlling portions which are adapted to control the direction of plastic deformation of the deformable portion. The deformation controlling portions have such a configuration and shape that, when a compression load equal to or greater than a predetermined value is input to the main body in a tube axis direction, the deformable portion undergoes plastic deformation in at least one of a radially outward direction and a radially inward direction of the main body concurrently with the compressive plastic deformation in the tube axis direction.

摘要： A metal plating applied on a joining portion of a first metal member is heated before a rotating tool under rotation being pressed against a second metal member. Herein, the rotating tool under rotation starts being pressed against the second metal member when the metal plating is heated at least up to a specified temperature that is high enough to make the metal plating in a softened solid state. Thereby, a properly-high joining strength can be provided in a frictional joining of a metal member with a metal plating thereon and another metal member.

摘要： In the third step of joining of the metal members, the pressing force of the rotational tool under rotation is maintained at the third pressing force that is smaller than the second pressing force until a specified period of time elapses after the tip of the pin portion of the rotational tool has reached the specified point that is at a distance from the joining face. Accordingly, the proper plastic flow of the metal member can be generated and thereby the joining strength with a sufficient period of time of agitation can be ensured, by maintaining a high temperature enough to soften the metal member and by preventing the rotational tool from coming into the metal member too deeply or from penetrating the metal member.

摘要： A crash can is made of aluminum-alloy casting and provided between a side frame extending in a vehicle longitudinal direction at a side portion of a vehicle and an end portion of a bumper reinforcement extending in a vehicle width direction. The crash can comprises a hollow tube portion extending in the vehicle longitudinal direction and having a cross-shaped section. At least one of an outwardly-projecting corner portion and an inwardly-projecting corner portion of the tube portion is formed by a groove such that a thickness thereof is thinner than that of the other portion of the tube portion. Accordingly, an impact which a vehicle body or a passenger may receive in a vehicle collision can be reduced by the crash can.

摘要： An aluminum plate and a steel plate are lapped. A rotating tool is placed on the aluminum plate, and then a pressing force and a rotational force around a pressing axis of the rotating tool are applied to the aluminum plate and the steel plate. A zinc plating layer having oxidation-prevention function is formed on the surface of the steel plate in advance. When joining the both plates, an oxidation film formed on the aluminum plate is destroyed and the zinc plating layer is pushed out outward from a joining portion, by applying the above pressing force and frictional heat and plastic flow due to the rotation of the rotating tool. Thereby, respective new uncovered surfaces of the both plates are directly contacted.

摘要： In step S5, the pressing force of a rotating tool is maintained at a first pressing force. Namely, the frictional heat due to the rotation of the rotating tool is generated on a surface of an aluminum plate, and the aluminum plate is softened by this frictional heat. Accordingly, the centering of a pin portion of the rotating tool can be attained surely. Thus, even if the pin of the rotating tool is short, a stable joining position can be obtained, so that the aluminum material can be prevented from being accumulated on the rotating tool, the appearance of joining surfaces can be prevented from deteriorating, and the sufficient joining strength can be obtained as well.

Herein, the rotating tool under rotation starts being pressed against the second metal member when the metal plating is heated at least up to a specified temperature that is high enough to make the metal plating in a softened solid state.
