An engine unit includes an engine having a crank shaft, the belt type CVT, a clutch, an output shaft and a generator. The CVT has a primary sheave, a secondary sheave shaft and a secondary sheave. The primary sheave is on one side of the crank shaft and the clutch is on another side with respect to the secondary sheave on the secondary sheave shaft. The output shaft is on a side opposite to the clutch on the secondary sheave shaft. The generator is on the other side of the crank shaft. A center axis of rotation of the secondary sheave shaft is higher than a center axis of rotation of the crank shaft. Right and left footsteps are located behind a rear end of the rotation motor and under a lower end of the secondary sheave.
