The urea tank for a selective catalyst reduction device may comprise: a main tank body that stores urea that is provided to a selective catalyst reduction device; a urea filler neck connected to the main tank body to enable injection of urea into the tank body; and a valve unit which is installed on the upper surface of the main tank body, recirculates ammonia gas into the urea filler neck when urea is injected, and selectively discharges high-pressure ammonia gas. |
