To prevent a reducer supplied to a reducer tank from being affected by heat generated from an exhaust passage.SOLUTION: A reducer injection port structure in a vehicle 1 having an exhaust purification device for purifying an exhaust gas by injecting a reducer to an exhaust passage 12 includes: a reducer tank 13 which stores the reducer; a supply port 31 which supplies the reducer to the reducer tank 13; and a supply tube 21 which connects the reducer tank 13 and the supply port 31. The exhaust passage 12 is arranged on one side in a vehicle width direction with respect to the reducer tank 13, and the supply port 31 and the supply tube 21 are arranged on the other side in the vehicle width direction with respect to a center in the vehicle width direction of the reducer tank 13.SELECTED DRAWING: Figure 1
【課題】還元剤タンクに補給する還元剤が排気通路の発する熱の影響を受けないようにする。【解決手段】還元剤を排気通路12に注入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、還元剤タンク13に還元剤を補給するための補給口31と、還元剤タンク13と前記補給口31とを接続する補給管21とを備え、排気通路12が還元剤タンク13に対して車幅方向の一方側に配置されるとともに補給口31及び補給管21が還元剤タンク13の車幅方向中央より車幅方向の他方側に配置される。【選択図】図1
