PURPOSE: A urea dispersion device for a selective catalyst reductor is provided to evenly disperse exhaust gas and urea of liquid state and to maintain engine performance by minimizing rising of back pressure in high temperature. CONSTITUTION: A urea dispersion device for a selective catalyst reductor comprises an installation port(10), a lattice plate(30), and a wing member(50). The installation port is circular hollow pipe and is installed in an exhaust pipe. The lattice plate comprises a horizontal plate(31) and a vertical plate(35) and is fixed to the inner surface of the installation port to efficiently disperse exhaust gas and urea. The wing member is formed at the lattice plate and disperses the exhaust gas and the urea discharged through an injector.
