PROBLEM TO BE SOLVED: To provide a door impact beam for a vehicle which is high in rigidity, light in weight and low in expense.SOLUTION: A door impact beam for a vehicle has a first groove part, a second groove part and a connection wall part. The first groove part and second groove part extend to a prescribed direction along a first door panel, and are opened toward a second door panel side. The second groove part is formed in a width direction of the first groove part with a prescribed interval. The connection wall part extends to the prescribed direction along the second door panel. The connection wall part connects one side wall part of the first groove part and one side wall part of the second groove part. The first groove part has a protrusion which protrudes from an end part at the second door part side to the inside of the first groove part at the other side wall part, and extends to the prescribed direction. The second groove part has a protrusion which protrudes from the end part at the second door panel side to the inside of the second groove part at the other side wall part, and extends to the prescribed direction. The first groove part, second groove part and connection wall part are integrally formed by an extrusion molding method.SELECTED DRAWING: Figure 4 |
