Abstract
A vehicle door frame includes an outer member and an elongated inner member. The inner member includes an extended portion, which extends in an outward direction of the vehicle, and an edge portion, which includes a distal end surface. A protrusion is formed on the distal end surface. The protrusion protrudes in the outward direction of the vehicle and is located at a predetermined position of the inner member in the longitudinal direction. The folded portion has a facing portion that faces the distal end surface. The protrusion can be melted by heating by the concentration of electric current during resistance welding and is configured to pressurize and join the distal end surface and the facing portion of the folded portion to each other. The protrusion includes a tip end, which has an arcuate cross section protruding in the outward direction of the vehicle.
