Subframe structure
A subframe structure includes: a left-right pair of extension members extending in a vehicle front-rear direction and each having a rectangular orthogonal cross section; a rear member connected to rear end portions of the extension members and extending in a vehicle width direction; and connecting parts connecting the rear end portions and the rear member. Each extension member includes: a first weak portion located forwardly of the corresponding connecting part and deformable when a load is applied; and a second weak portion located forwardly of the first weak portion and deformable when a load is applied. The first and second weak portions of each extension member are formed in upper and lower faces thereof, respectively. The orthogonal cross section of each extension member has a height, dimension H1 at the first weak portion and a height dimension H2 at the second weak portion and H1 is smaller than H2.
