To improve insufficient lubrication due to imbalance of an oil supply amount resulting from helical gears especially at low speed, while reducing an oil level of an oil storage part in a transfer device.SOLUTION: A transfer structure of a vehicle comprises a power transmission mechanism composed of a first gear 21 and a second gear 22 formed as helical gears meshing with each other. The transfer structure is provided with oil paths 91 and 94 that comprise: an oil receiving part 95 provided on the rear side in a rotation direction of the meshing part of the second gear 22 with the first gear 21, for receiving lubricant scraped up and scattered by the second gear 22 on its upper surface; and oil guide 96 that is inclined downward from the downstream position of the oil receiving part 95, and guides the lubricant to a bearing 81 of the first gear 21 provided on the front side in a rotational direction of the second gear 22 in a helical direction.SELECTED DRAWING: Figure 3
【課題】トランスファ装置のオイル貯留部のオイルレベルの低減をはかりつつ、ヘリカルギヤによるオイル供給量のアンバランスによる潤滑不足の特に低速時での改善を図る。【解決手段】互いに噛合するヘリカルギヤで形成される第1ギヤ21と第2ギヤ22とから成る動力伝達機構を備える。第2ギヤ22の第1ギヤ21との噛み合い部の回転方向後方側に、第2ギヤ22が掻き上げ飛散した潤滑油を上面に受けるオイル受け部95と、該オイル受け部95の下流位置から下方に傾斜し、第2ギヤ22のヘリカル方向における回転方向の前方側となる側に設けられた第1ギヤ21の軸受81に潤滑油を案内するオイル案内部96とを備えたオイルパス91,94を設けた。【選択図】図3
