Abstract: In a lower member of a subframe for a vehicle, a middle portion between an outer-side portion and an inner-side portion includes an outer-side curved bottom portion and an inner-side curved bottom portion. Adjacently-positioned closed cross-sections are provided corresponding to at least a portion of the outer-side curved bottom portion and the inner-side curved bottom portion, the adjacently-positioned closed cross-sections being made up of a first closed cross-section of a first crossmember and a second closed cross-section of the lower member positioned adjacent to each other in a vertical direction in such a manner as to be divided by a wall portion of the first crossmember and next to each other, the wall portion defining the first closed cross-section.
