PROBLEM TO BE SOLVED: To provide a layout structure for a vehicular reducing agent supply device capable of suppressing an increase in a temperature of a liquid reducing agent that reaches an injection valve and of reducing damage of reducing agent piping.SOLUTION: A layout structure is for a reducing agent supply device that is mounted to an automobile, pressure-feeds a liquid reducing agent stored in a tank to purify exhaust gas to an injection valve and injects the liquid reducing agent by using the injection valve. The tank is provided on the rear side of the automobile and the injection valve is provided on the front side of the automobile. At least part of reducing agent piping passing through a region in the vehicle body longitudinal direction where a cabin is located out of reducing agent piping for connecting the tank with the injection valve is disposed in a vehicle body.SELECTED DRAWING: Figure 1
【課題】噴射弁に到達する液体還元剤の温度の上昇を抑制し、かつ、還元剤配管の破損を低減可能な、車両の還元剤供給装置のレイアウト構造を提供する。【解決手段】乗用車に搭載され、タンク内に貯蔵された排気ガス浄化用の液体還元剤を噴射弁に圧送し、噴射弁により液体還元剤を噴射する還元剤供給装置のレイアウト構造であって、タンクは、乗用車のリア側に備えられ、噴射弁は、乗用車のフロント側に備えられ、タンクと噴射弁とを接続する還元剤配管のうち、車体前後方向における車室が位置する領域を通過する還元剤配管の少なくとも一部を、車体内部に配置する。【選択図】図1
