A motor vehicle rear structure includes an underframe component to support a motor vehicle floor and in which a tunnel is formed, an axle component including a central part and two lateral parts that define a space to accommodate a component of the vehicle, an articulation device including a first articulation element and a second articulation element which are able to pivot relative to one another, and at least one front reinforcing element fixed to the second articulation element and to the tunnel. The rear structure is arranged in such a way that said at least one front reinforcing element allows at least some of a load in the direction of travel of the motor vehicle derived from the axle component to be transmitted to the tunnel.
