PROBLEM TO BE SOLVED: To provide a lubrication structure for a hybrid vehicle that enables oil to be supplied appropriately to a gear transmission mechanism for transmitting outputs from an engine and a motor to a driving shaft side.SOLUTION: In a lubrication structure for a hybrid vehicle using an engine, a first motor 2 and a second motor as driving power sources and including: a planetary gear mechanism PG in which the first motor 2 is connected to a sun gear 6, an output shaft is connected to a ring gear 7 and the engine 1 is connected to a carrier 8; a brake mechanism 10 for selectively stopping and fixing the rotation of the carrier 8; an oil pump 21 operated by a third motor to generate hydraulic pressure; and an oil supply mechanism 22 that uses the oil pump 21 as a hydraulic source to supply oil to the planetary gear mechanism PG, the oil supply mechanism 22 is configured to pressure-feed the oil to an axial center portion of a pinion gear 9 of the planetary gear mechanism PG by generating hydraulic pressure by using the oil pump 21.SELECTED DRAWING: Figure 2

    【課題】エンジンおよびモータの出力を駆動軸側へ伝達する歯車伝動機構に対してオイルを適切に供給することができるハイブリッド車両の潤滑構造を提供すること。【解決手段】エンジンならびに第1モータ2および第2モータを駆動力源とし、サンギヤ6に第1モータ2が連結され、リングギヤ7に出力軸が連結され、キャリア8にエンジン1が連結された遊星歯車機構PGと、選択的にキャリア8の回転を止めて固定するブレーキ機構10と、第3モータにより駆動されて油圧を発生するオイルポンプ21と、オイルポンプ21を油圧源にして遊星歯車機構PGへオイルを供給するオイル供給機構22とを備えたハイブリッド車両の潤滑構造において、オイル供給機構22を、オイルポンプ21で油圧を発生させることにより、遊星歯車機構PGのピニオンギヤ9の軸心部分へ、オイルを圧送するように構成する。【選択図】図2
