PURPOSE: An exhaust device of construction equipment restricts a high exhaust resistance because an uneven part at the exit of an exhaust pipe does not interfere with discharge of exhaust gas. CONSTITUTION: An exhaust device of construction equipment comprises a post processing device(12), an exhaust pipe(10), and an uneven part(11). The exhaust device of the construction equipment is installed inside a swing device of the construction equipment. The post processing device post-processes the exhaust gas of an engine. The exhaust pipe discharges the exhaust gas from the exhaust pipe to outside. The uneven part, comprising a plurality of concaves and convexes in the discharge direction of exhaust gas, is formed on the inner surface of the exhaust pipe. The uneven part comprises concaves and convexes crossing the flow direction of exhaust gas at least. |
