REDUCTANT INJECTION PORT STRUCTURE

To prevent a reductant spilling from a supply port from being solidified and deposited.SOLUTION: A 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; a supply pipe 21 connecting a supply port 31 which supplies the reductant with the reductant tank 13; a reductant receiving part 32 which is disposed around the supply pipe 21 and receives the reductant leaking from the supply port 31; and a discharge port 33 which discharges the reductant leaking to the reductant receiving part 32 from the reductant receiving part 32.SELECTED DRAWING: Figure 3 【課題】補給口から零れた還元剤が固形化して堆積するのを防ぐ。【解決手段】排気通路１２に還元剤を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、還元剤を補給する補給口３１と還元剤タンク１３とを接続する補給管２１と、補給管２１の管周りに配置され、補給口３１から漏れた還元剤を受ける還元剤受け部３２と、還元剤受け部３２に漏れた還元剤を還元剤受け部３２から排出する排出口３３とを備えて成る。【選択図】図３
