Abstract
The present invention is an exhaust gas flow rate measuring unit that eliminates the disturbance of the flow velocity distribution of exhaust gas flowing through an attachment pipe to accurately measure an exhaust gas flow rate, and is mounted in a vehicle to measure the flow rate of exhaust gas emitted from an exhaust pipe of the vehicle. In addition, the exhaust gas flow rate measuring unit includes the attachment pipe that is connected to the exhaust pipe and forms a flow path through which the exhaust gas flows, a flowmeter that is provided in the flow path and measures the flow rate of the exhaust gas flowing through the flow path, and a straightening mechanism that is provided on the upstream side of the flowmeter in the flow path.
