Abstract: PURPOSE: A catalytic reduction device is provided to mix exhaust gas with reducing agents at an optimal ratio rate as the movement of a vale body is controlled as a parameter. CONSTITUTION: A catalytic reduction device(800) comprises an expanded part, a swirling unit(820), and a reducing agent jetting unit(830). The expanded part is formed in an exhaust pipe(810), and placed in a predetermined section from the upper side to the lower side. The swirling unit is installed inside the expanded part in a coaxial direction, and changes an exhaust passage area by a valve body(822) moving in proportion to exhaust pressure. The swirling unit swirls exhaust gas. The reducing agent jetting unit jets reducing agents to the whirling exhaust gas.
