Lubricating device for change-speed gearing units

摘要

In a change-speed gearing unit including an extension housing formed at its rear end portion with an upright projection located in the upper opening of the housing, and a shift-and-select lever shaft slidably and rotatably supported at its rear end portion by an axial bearing hole in the upright projection, a lubricating device comprises a pair of laterally upright walls formed on the rear end portion of the housing between both faces of the upright projection and both opposed inner walls of the upper opening portion of the housing to form an oil well in open communication with the axial bearing hole, the oil well being supplied with lubricating oil picked up by the rearmost gears of the change-speed gearing unit.
