Suspension subframe structure of vehicle

A suspension subframe structure of a vehicle for supporting a plurality of suspension arms of a pair of right and left multi-link suspension systems, comprising:

• first and second lateral members provided in spaced-apart relation to each other in a longitudinal direction of a vehicle body and each extending in a lateral direction of the vehicle body;
• a pair of longitudinal members extending in the longitudinal direction in such a manner that one of the longitudinal members connects respective left ends of the first and second lateral members, and the other longitudinal member connects respective right ends of the first and second lateral members;
• and
• right and left inclined members each having one end which is located on the side of a respective one of the right and left ends of the first lateral member and provided with an upper-arm support portion and a lower-arm support portion, each of the right and left inclined members extending obliquely relative to the lateral direction in top plan view to connect the upper-arm support portion and the lower-arm support portion with a laterally intermediate portion of the second lateral member.

• a pair of right and left upper-arm support portions provided in respective ones of the right and left ends of the first lateral member;
• a pair of right and left lower-arm support portions provided in respective ones of the right and left ends of the first lateral member;
• and
• right and left inclined members each extending obliquely relative to the lateral direction in top plan view to connect a respective one of the right and left ends or end-adjacent portions of the first lateral member with the laterally intermediate portion of the second lateral member,
• wherein each of the inclined members includes an upper sub-member and a lower sub-member, the upper sub-member is connected with the upper arm support portions or adjacent portions of the first lateral member, and the lower sub-member connects the lower-arm support portions or adjacent portions of the first lateral member with the second lateral member.
