PROBLEM TO BE SOLVED: To realize a structure for a vehicle having a closing plate 8 that covers equipment under a floor of a vehicle body 1a installed, where a cooling unit 4a of a power converter 2a efficiently radiates heat. SOLUTION: In an underfloor equipment arrangement, the equipment including the power converter 2a, of which a condenser 4a for a semiconductor element 3 is provided on the vehicle body side, is disposed on the underfloor of a railroad vehicle 1a, and the closing plate 8 is provided to cover the vehicle body side of the equipment. The inner wall of the closing plate 8 is mechanically connected to a heat radiation part 6a of the condenser 4a so that the condenser 4a for the semiconductor element 3 is thermally connected to the closing plate 8 provided to cover the vehicle body side as well, allowing the closing plate 8 functioning as a part of the condenser.
