MOTOR DRIVING FORCE TRANSMITTING DEVICE

PROBLEM TO BE SOLVED: To stably supply lubricating oil to a plurality of gears even if the plurality of gears are vertically arranged, and to reduce a torque loss caused by the agitation of the lubrication oil by the gears. SOLUTION: In a transmission casing 3, the drive gear 8 to which a driving force of a motor 1 is transmitted, and the driven gears 12a, 12b and 12c engaged with the drive gear 8 and driving hydraulic pumps 13, 14, etc., are arranged, the driven gear 12a is arranged to face an oil pan 3a, the driven gears 12b, 12c are arranged above the driven gear 12a, and also a partition wall is formed which is arranged to surround the driven gear 12a and can guide the lubricating oil 4 stored in the oil pan 3a accompanied by the rotation of the driven gear 12a to vicinities of the driven gears 12b, 12c. The partition wall includes a first partition wall 16 and a second partition wall 17 which are arranged so as to oppose each other to sandwich the driven gear 12a, and an inflow opening 18 into which the lubricating oil 4 in the oil pan 3a is led to flow is formed between lower ends of the partition walls.
