This exhaust gas purification device is provided with a pre-oxidation catalyst which is disposed in an exhaust gas passage located immediately after an engine mounted on a vehicle; and a muffler which is provided around the pre-oxidation catalyst and which reduces the noise of exhaust gas generated by the engine and discharges the exhaust gas. The muffler is configured to have an inlet which is connected to an upstream exhaust pipe located immediately after the engine and into which exhaust gas flows; and an outlet which is connected to a downstream exhaust pipe and from which the exhaust gas flowing into the muffler from the inlet is discharged after passing through the pre-oxidation catalyst.
