Disclosed is a urea injection device for a selective catalyst reduction device. The urea injection device for a selective catalyst reduction device serves to inject urea into a urea tank through a urea injection port and a urea injection line that connects the urea injection port and the urea tank. The urea injection device may include: i) a leveling pipe which is connected with the urea tank, ii) a separator which is installed to be connected with the leveling pipe, and connected to the urea injection port through a gas recirculation line, iii) a gas vent line which is connected with the separator, and iv) a check valve which is installed in the gas vent line.
