FIELD: transport.
SUBSTANCE: roof contains roof panel (4) which has smooth outer supporting surface for outer roof shell and inner surface (13) with reinforcing carcass (15) containing multiple reinforcing ribs (16) protruding from the inner surface (13). Optimised roof panel structure differs in the fact that inner surface (13) and reinforcing ribs (16) of reinforcing carcass (15) are covered with flat yielding element (17). The yielding element (17) has multiple chute-shaped grooves (18) to accommodate reinforcing ribs (16).
EFFECT: structure optimisation.
