A structure for an underrun protector is provided, which enables the occurrence of buckling to be inhibited, and with which weight is suppressed, and costs are curbed. In this structure for an underrun protector (10) to be attached to brackets on a front section or a rear section of a vehicle-body frame, an outside panel (20) which is made of steel plate, is disposed outside in a front-rear direction of a vehicle, and has a channel-shaped cross section, and an inside panel (30) which is made of steel plate, is disposed inside in the front-rear direction of the vehicle, and has a channel-shaped cross section are coupled so as to be provided with coupled overlapping parts (91) where edge sections (22a, 23a, 32a, 33a) of respective flange sections (22, 23, 32, 33) overlap. Inside a hollow portion in coupling areas where the underrun protector (10) is coupled to each of the brackets, reinforcement panels (40) made of steel plate are coupled so as to overlap the coupled overlapping parts (91) and an inner surface of either the inside panel (30) or the outside panel (20), and, as a result, multiple-panel parts (85) having at least 3 layers are formed. |
