Abstract

This invention is an exhaust gas sampling device that samples an exhaust gas by the use of an open-type exhaust gas sampling part and that is for reducing leakage of the exhaust gas produced due to unevenness of flow velocity of a cooling wind around an exhaust gas pipe. The exhaust gas sampling device comprises the exhaust gas sampling part that has an exhaust gas sampling port arranged to face an exhaust gas discharging port of the exhaust gas pipe and that samples the exhaust gas emitted from the exhaust gas discharging port and an ambient gas surrounding the exhaust gas pipe, and the exhaust gas sampling part has an involvement decreasing structure that decreases the exhaust gas flowing out from the exhaust gas sampling port due to involvement of the exhaust gas by the ambient gas that flows in from the exhaust gas sampling port.
