Abstract
An exhaust-gas purification device disposition structure of a vehicle, comprises a fuel tank with a fuel supply port which is disposed so as to be open to an outside of a vehicle compartment, and a urea tank to accommodate urea water solution as deoxidizer to purify exhaust gas. The urea tank is disposed outside the vehicle compartment, and a pouring port of the urea tank is provided inside the vehicle compartment. Accordingly, the urea water solution can be surely prevented from entering into the vehicle compartment even in case of the breakage of the urea tank, and the mistake of supplying the wrong liquid into the wrong supply (pouring) port tank which may be made by confusing the ports can be avoided.
