Abstract
There is provided an underbody structure capable of exactly distributing and transmitting a front collision load to front and back skeleton portions of an underbody even in a case where the front collision load to be input from the front of a vehicle is concentrated on one side in a vehicle width direction. When a power unit 1 moves rearward due to an offset collision load of a right front face of a vehicle, a right connecting arm 7G of a sub-frame 7, an engine rear mount 7E, and right and left stoppers 7H and 7I receive an offset collision load from the power unit 1, thereby suppressing generation of an unintended rotative force in the power unit 1. The sub-frame 7 distributedly transmits an offset collision load to a rear portion 4A of a right front side member 4, and right and left tunnel reinforcements 5 and 5 mainly through four paths of a right beam 7D, a right load transmission beam 7J2, and right and left load transmission beams 7J3 and 7J4 of an intermediate portion.
