Abstract
In a transmission including a transmission casing, a rotational speed changing mechanism, and a differential mechanism which has a differential power input gear, a power output shaft transmits the rotary power output of the rotational speed changing mechanism to the differential mechanism via a power output gear provided at its one end and meshing with the differential power input gear. This power output shaft is formed with a first lubricant passage extending from its one end opening at the one end of the power output shaft to the other end opening to a point on its side surface. A bearing rotatably supports a part of the power output shaft proximate to the power output gear from the transmission casing. This bearing is located close to the abovementioned point on the side surface of the power output shaft. A lubricant collecting and directing member, provided as mounted to the transmission casing, includes an extension portion which extends into that one end of the abovementioned first lubricant passage from its open end, a collection portion for collecting lubricant stirred up by the differential power input gear, and a second lubricant passage which communicates the collection portion with the extension portion. The lubricant collected by the collection portion is thus supplied to the first lubricant passage and then to the bearing.
