PROBLEM TO BE SOLVED: To provide a vehicle underfloor structure capable of preventing an equipment provided at the periphery of a DPF device from being overheated by heat during manual regeneration of the DPF device. SOLUTION: In a vehicle lower part structure in which both sides in the vehicle width direction are surrounded by a vehicle body side wall under the floor of the vehicle, a capacitor is mounted between the vehicle body side wall and the DPF device for purifying exhaust gas of a vehicle engine so that a flow of exhaust air of a capacitor fan of a vehicle air conditioner flows on the vehicle width direction inner side and along the floor face, and a baffle for guiding a flow of exhaust air to the periphery of the capacitor is provided. Thus, when a fan is driven, air around the DPF device is replaced, preventing stay of hot air under the floor and overheating of the peripheral equipment. COPYRIGHT: (C)2008,JPO&INPIT
