摘要： PROBLEM TO BE SOLVED: To prevent a reducer from entering into a vehicle compartment even if a reducer tank breaks when the reducer tank is disposed on a vehicle, avoid harmful influence on steering stability of the vehicle, to suitably set position relation between a fuel tank and an exhaust pipe, and to inhibit harmful influence on vibration characteristics of a floor panel during vehicle travel. SOLUTION: A vehicle comprising an exhaust-gas purification device 70 forming ammonia as reduction material for purifying components in exhaust gas by thermally decomposing urea water solution which is less toxic than ammonia and more fire-resistant than fuel, and purifying exhaust gas using the formed ammonia, is provided with a fuel tank 51, an urea tank 71 to accommodate urea water solution, and an exhaust system extending in a vehicle fore-and-aft direction and having an exhaust port 68 at a rear end, below a floor panel 2. The urea tank is disposed at a section behind the fuel tank and separated by a predetermined gap G in a vehicle lateral direction with respect to a silencer 66 of the exhaust system.
