Abstract
There is provided a vehicle subframe (1) in which a projecting portion (24, 31) of a front member (20) extends upward, while projecting from a body portion in a width direction, to have an upper end (25, 32), and exhibits a convex shape toward a front side, with the upper end (25, 32) functioning as a front attachment portion to a vehicle body, in such a manner that support stiffness of a suspension can be improved, while ensuring favorable productivity, high strength, and the like, with a simple configuration.
