[Problem] To provide a transmission having a lubrication construction which is capable of efficiently supplying scooped-up lubrication oil to respective lubrication portions and which is little in power loss. [Solution] The transmission is provided with shaft members rotatably carried in a case 10 to extend in an axial direction, a plurality of gears supported on the shaft members and drivingly connectable to the shaft members by shift clutches, a large-diameter gear 80 included in the plurality of gears and soaked at its lower part in lubrication oil contained in a lubrication oil storage region 91 formed at a lower portion of the case 10 for scooping up the lubrication oil when rotated, and a receiver 92 arranged to extend in the direction of a rotational axis for the large-diameter gear 80 for collecting the scooped-up lubrication oil and for flowing the collected lubrication oil toward lubrication portions, wherein the receiver 92 has a vertical wall 92d 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 94 which enables the lubrication oil splashing toward between the receiver 92 and the large-diameter gear 80 to flow on a surface thereof and to be introduced to the collecting portion 92a by the inertia force thereof.
