Zusammenfassung:PROBLEM TO BE SOLVED: To provide a drive unit which prevents oil leakage.SOLUTION: A drive unit includes: a carrier part 30 which supports a pinion gear 38; a reduction mechanism 120 in which an introduction passage 43 for introducing a lubricant is formed at the carrier part 30; a transaxle case 12 for accommodating the reduction mechanism 120; and a plate 51 arranged between the reduction mechanism 120 and the transaxle case 12. The transaxle case 12 has an opposing face 13 which opposes the plate 51, and on which a groove-shaped oil passage 41 is formed. The plate 51 includes: a flat plate part 52 extending in a flat plate shape; a disc spring mechanism part 53 which is arranged at a peripheral edge of the flat plate part 52, and generates an elastic force so as to energize the flat plate part 52 toward the opposing face 13; and a gutter-shaped guide part 54 which is arranged at the flat plate part 52, and introduces the lubricant flowing in the oil passage 41 to the introduction passage 43. 【課題】油漏れの発生を防止する駆動装置、を提供する。【解決手段】駆動装置は、ピニオンギヤ38を支持するキャリア部30を有し、潤滑油を導入するための導入路43がキャリア部30に形成されるリダクション機構120と、リダクション機構120を収容するトランスアクスルケース12と、リダクション機構120およびトランスアクスルケース12の間に配置されるプレート51とを備える。トランスアクスルケース12は、プレート51と対向し、溝状の油路41が形成される対向面13を有する。プレート51は、平板状に延在する平板部52と、平板部52の周縁に設けられ、平板部52を対向面13に向けて付勢するように弾性力を発生する皿バネ機構部53と、平板部52に設けられ、油路41に流れる潤滑油を導入路43に導く樋状のガイド部54とを有する。【選択図】図2
