A mounting structure for the front end of a car or small truck has a frame-shaped structure that surrounds an air cooled pass-through area and exhibits an upper crossmember, a lower crossmember and sidemembers connecting them. The upper crossmember is designed as a closed wall for receiving a hood lock and forms a sealing rib that borders on the air cooled pass-through area for an air-blocking connection of a radiator component. To provide the upper crossmember as the lock crossmember at the mounting structure with a high moment of inertia and to reduce the air cooled pass-through area only to a negligible degree, the upper crossmember is strutted using a lattice structure that is adjacent to the sealing rib and protrudes into the air cooled pass-through area, where the lattice openings form a part of the air cooled pass-through area with their entire opening area.
