A vehicular power unit provided with an engine (E) in which a crankshaft is rotatably supported by a crankcase and a transmission (M) housed in the crankcase for shifting power transmitted from the crankshaft, the vehicular power unit comprising:

• a drive-side transmission sprocket wheel provided to an end of an output shaft of the transmission (M) that protrudes from one side of the crankcase;
• an endless transmission belt wound around the drive-side transmission sprocket wheel, the endless transmission belt for transmitting power to a driving wheel;
• a generator cover for covering a generator facing the one side of the crankcase;
• and
• a protective cover for covering the driving wheel facing the one side of the crankcase,
• wherein the generator cover and the protective cover are disposed at positions where they partially overlap with each other in an arranging direction on a side view.
