An exhaust gas purification device includes a pre-oxidation catalyst disposed in an exhaust gas passage disposed right next to an engine mounted in a vehicle body and a muffler that is provided in such a manner as to surround the pre-oxidation catalyst, and discharges exhaust gas generated in the engine while reducing noise. The muffler has an inlet which is connected to an upstream side exhaust pipe right next to the engine, and into which the exhaust gas is introduced, and an outlet which is connected to a downstream side exhaust pipe, and from which the exhaust gas introduced from the inlet is discharged through the pre-oxidation catalyst.
