  • Publication number: 20120096968
    Abstract: In a transmission, a large-diameter gear included in a plurality of gears on rotatable shaft members is soaked at its lower part in lubrication oil contained in a lubrication oil storage region formed at a lower portion of a case and scoops up the lubrication oil when rotated. A receiver extending in the axial direction of the large-diameter gear collects the scooped-up lubrication oil and flows the collected lubrication oil toward lubrication portions. The receiver has a vertical wall which enables the lubrication oil scooped up and splashing above the receiver to collide therewith, to flow down on a surface thereof and to be introduced to a collecting portion of the receiver, and an introducing portion which enables the lubrication oil splashing toward between the receiver and the large-diameter gear to flow on a surface thereof and to be introduced to the collecting portion by the inertia force thereof.
