摘要

A motorized two-wheeled vehicle is disclosed having a power transmission casing which comprises a main casing body (6) extending rearwardly laterally of the body from one side of the engine (4) of the vehicle to one side of the driven rear ground wheel (3) of the vehicle and rotatably supporting a wheel axle (5) of the rear wheel. The main body has fitted to it in liquid-tight manner a reduction gear mechanism cover (10) so that a reduction gear mechanism (9) contained in this part of the main body (6) can be immersed in oil. Also fitted to the main body is a V-belt transmission cover (16) and a V-belt transmission (15) of dry type is contained in this part of the main body (6). …The casing as a whole is small-sized and as the reduction gear mechanism is immersed in lubricating oil it is always well lubricated.
