To secure a predetermined distance between a reductant tank and the ground and secure a sufficient volumetric capacity of the reductant tank.SOLUTION: An reductant injection port structure in a vehicle 1 including an exhaust emission control device which injects a reductant to an exhaust passage 12 to purify an exhaust gas includes: a reductant tank 13 which stores a reductant; and a supply pipe 21 which supplies the reductant to the reductant tank 13 from a supply port 31 provided at one end. The supply pipe 21 has a first supply pipe part extending from the supply port 31 in a vertical direction of the vehicle 1. The first supply pipe part is disposed at the side of the reductant tank 13.SELECTED DRAWING: Figure 1
【課題】還元剤タンクと地上との間に所定の距離を確保しつつ、還元剤タンクの十分な容積を確保する。【解決手段】還元剤を排気通路12に噴射して排気ガスを浄化する排気浄化装置を備えた車両1における還元剤注入口構造であって、還元剤を貯留する還元剤タンク13と、一端に設けられた補給口31から還元剤タンク13に還元剤を補給する補給管21と、を備え、補給管21は、補給口31から車両1の上下方向に延びる第一補給管部を有し、第一補給管部は、還元剤タンク13の側方に配置される。【選択図】図1
