To stabilize a lubricant amount of a coupling chamber to maintain a cooling effect of a coupling due to agitation of lubricant, regardless of inclination of a vehicle in a front-back direction, even in a situation where the level of lubricant is lowered to reduce agitation resistance.SOLUTION: A transfer structure of a vehicle comprises a gear chamber Z1 that houses a first gear 13 and a second gear 14 meshing with each other, and a coupling chamber Z2 that houses a coupling 20 provided coaxially with the first gear 13. The transfer structure comprises an introduction path 90 that introduces lubricant in the gear chamber Z1 to the coupling chamber Z2, and return paths 94, 95, 96, 91 that returns the lubricant introduced into the coupling chamber Z2 to the gear chamber Z1. The return path inclines downward toward the gear chamber Z1 from an opening part 94 that opens at the lower part of the middle part of the coupling chamber Z2 in a vehicle front-rear direction to an oil discharge hole 95 that opens at the gear chamber Z1.SELECTED DRAWING: Figure 13

    【課題】潤滑油を低レベル化して撹拌抵抗を低減した状況であっても、車両の前後方向の傾斜に拘わらず、カップリング室の潤滑油量が安定し、潤滑油の撹拌によるカップリングの冷却効果を維持する。【解決手段】互いに噛合する第1ギヤ13と第2ギヤ14とを収容するギア室Z1と、第1ギヤ13と同軸上に設けられたカップリング20を収容するカップリング室Z2とを備える。ギヤ室Z1の潤滑油をカップリング室Z2に導入する導入経路90と、カップリング室Z2に導入された潤滑油をギヤ室Z1に戻す戻し経路94,95,96,91とを備える。戻し経路は、カップリング室Z2の車両前後方向中間部の下部に開口する開口部94から、ギヤ室Z1に開口するオイル排出孔95までギヤ室Z1に向けて下方に傾斜している。【選択図】図13
