To provide a vehicle power transmission device which enables improvement of rigidity of a power transmission case while inhibiting increase in the weight of the power transmission case and the number of components and can inhibit deformation and vibration of the power transmission case.SOLUTION: In a power transmission device 2, a cylindrical oil passage part 48 which expands from a rear wall 18 of a power transmission case 4 to the outer side in an axial direction and has oil passages 49c, 50a, 51a therein is formed at the power transmission case 4. A first oil passage part 49 of the oil passage part 48 extends substantially parallel to a direction in which tangential force F1 of an engagement part 23 between a final drive gear 21 and a final driven gear 22 is generated.SELECTED DRAWING: Figure 3
【課題】動力伝達ケースの重量や部品点数が増大することを抑制しつつ、動力伝達ケースの剛性を向上でき、動力伝達ケースの変形や振動を抑制できる車両用動力伝達装置を提供すること。【解決手段】動力伝達装置2において、動力伝達ケース4に、動力伝達ケース4の後壁18からの軸方向の外方に膨出し、内部にオイル通路49c、50a、51aを有する筒状のオイル通路部48が形成されており、オイル通路部48のうちの第1のオイル通路部49は、ファイナルドライブギヤ21とファイナルドリブンギヤ22との噛み合い部23の接線力F1が生じる方向と略平行に延びている。【選択図】図3
