PURPOSE: A vehicle exhaust gas reductant injection device is provided to complete task without dropping urea solution on a mat by drawing out a urea inlet port from the lower end of a seat during the injection of the urea solution. CONSTITUTION: A vehicle exhaust gas reductant injection device comprises an injection nozzle assembly, and a clamp assembly. The injection nozzle assembly is connected to a urea inlet port formed at the lower part of the seat. The injection nozzle assembly is composed of an injection nozzle(2). An injection nozzle has the elasticity to be shortly compressed to the fixed location or be drawn out. The clamp assembly is made of clamps. The clamp reduces the diameter surrounding the outer circumference of the inlet port or extends the diameter to release the inlet port.
