Abstract

The present invention is one that downsizes an exhaust gas sampling apparatus such as a CVS as well as uniforming temperature of diluted exhaust gas passing through a flow rate controller such as a critical flow venturi, and has a casing 10 formed with a gas introduction port PT3 for introducing the diluted exhaust gas and a gas lead-out port PT4 for leading out the diluted exhaust gas, in which a temperature regulating mechanism 2 is contained in the casing 10, the flow rate controller 31 is fluidly connected to the gas lead-out port PT4, and between the gas introduction port PT3 and the temperature regulating mechanism 2, a dispersion structure 12 that disperses the diluted exhaust gas introduced from the gas introduction port PT3 is provided.
