Shaft drive apparatus for motorized two-wheeled vehicle

摘要

An improvement in a shaft drive apparatus which is an outer casing extending over an liquid-tightly enclosing a torque damper on a propeller shaft which interconnects the output shaft of an internal combustion engine to a bevel gear mechanism on the rear wheel of a motorized two-wheeled vehicle. The casing is attached to the propeller shaft to rotate therewith. An outer covering can cover a universal joint which interconnects the torque damper and the input shaft of the bevel gear mechanism. The outer cover extends over and liquid-tightly surrounds the universal joint and engages the outer casing and has its interior in communication with an interior of the outer casing. The interior of the bevel gear casing can also communicate with the interior of the outer casing.
