Abstract

A small-sized vehicle, such as an ATV (All Terrain Vehicle), includes an engine having an output shaft, a front gear mechanism including a first shaft on a side of a front wheel to which a drive force from a front output shaft portion of the output shaft is transmitted, and a rear gear mechanism including a first shaft on a side of a rear wheel to which a drive force from a rear output shaft portion of the output shaft is transmitted. The front output shaft portion of the output shaft and the first shaft of the front gear mechanism are arranged substantially coaxial with each other, and the rear output shaft portion of the output shaft and the first shaft of the rear gear mechanism are arranged substantially coaxial with each other. The small-sized vehicle is capable of preventing vibrations and noise from being generated.
