  • Patent number: 11505250
    Abstract: Provided is a vehicle sub-frame including a front cross member, a rear cross member, and left and right side members mounted to connect the front cross member and the rear cross member to each other. Each of the left and right side members has a protrusion that protrudes laterally at a corner portion of a rear end portion thereof, the corner portion being joined to a corner portion of the rear cross member. A weld joint is formed by welding to the rear cross member along a laterally extending portion of a trim line portion of the protrusion, in which the trim line portion of the protrusion is the perimeter of the protrusion.
