A subframe for a vehicle satisfies durability and crash performance of a rear mounting portion during vehicle crash. The subframe may include an upper reinforcement and a lower reinforcement, which are spaced apart from each other and assembled to the subframe, and a rear mounting bracket connected to a chassis via a mounting bolt, wherein the lower reinforcement includes a bolt pushing-inducing trim line connected to a bolt hole and the upper reinforcement includes a pair of deformation-inducing holes formed on both front and rear of a pipe nut such that the mounting bolt is separated from an initial position and the upper reinforcement is deformed when an impact load is applied. |
