A straddle-type vehicle (1) according to the present invention includes a single-cylinder four-cycle engine (10). The engine (10) includes an exhaust gas re-circulation device (101). The exhaust gas re-circulation device (101) is communicated with an exhaust port (31). The exhaust gas comes into the storage container (100) in the exhaust gas re-circulation device (101) when the exhaust valve (32) is open in an exhaust stroke. When the exhaust valve (32) is open in an intake stroke after the top dead center, the exhaust gas is discharged from the storage container (100) into the combustion chamber (40).
