To dissolve a reducing solution in a reducing solution tank at an earlier stage by effectively using exhaust heat of an internal combustion engine, and to efficiently restrain volatilization of fuel in a fuel tank caused by the exhaust heat.SOLUTION: A tank arrangement structure for a vehicle includes an exhaust pipe (1) for discharging exhaust gas of an internal combustion engine to the atmosphere, a propeller shaft (3) for transmitting driving force to a rear wheel, a fuel tank (5) for storing liquid fuel of the internal combustion engine, and a reducing solution tank (2) for storing a reducing solution used for purifying nitrogen oxide in the exhaust gas, in a lower part of the vehicle. In a plan view, the fuel tank (5) is disposed in a side opposite from the exhaust pipe (1) with respect to the propeller shaft (3). The reducing solution tank (2) is disposed in a side opposite from the propeller shaft (3) with respect to the exhaust pipe (1).SELECTED DRAWING: Figure 1

    【課題】内燃機関の排熱を効果的に利用して還元液タンク内の還元液をより早期に溶かすと共に、上記排熱による燃料タンク内の燃料の揮発を効果的に抑止する。【解決手段】 車両用タンク配設構造は、内燃機関の排気を大気に排出するための排気管(1)と、後輪に駆動力を伝えるプロペラシャフト(3)と、内燃機関の液体燃料を貯める燃料タンク(5)と、排気中の窒素酸化物の浄化に用いる還元液を貯める還元液タンク(2)とを車両の下部に備えている。燃料タンク(5)は、平面視において、プロペラシャフト(3)に対して排気管(1)とは反対側に配置されている。還元液タンク(2)は、排気管(1)に対してプロペラシャフト(3)とは反対側に配置されている。【選択図】図1
