ABSTRACT:
A lubrication mechanism in a change-speed gearing unit in which an oil transfer trough is suspended in a fore-and-aft direction at one side of the inner wall of an extension housing secured at its front end to a transmission casing. The trough is fixed at its front end to the upper portion of the extension housing in such a way as to open toward the upper interior space of the transmission casing and fixed at its rear end to the rear portion of the side wall of the extension housing by means of a hollow bush of elastic material which is pressedly mounted within an axial groove in the rear portion of the side wall of the extension housing. The hollow bush is formed with a closed tubular portion coupled over the rear end of the trough and an outlet portion laterally extending from the tubular portion and opening toward the interior space above an oil well in the extension housing.
