To secure a sealing property with a simple configuration in an oil pump.SOLUTION: In an oil pump 52, a case cover 58 including a wall portion 68 and a pump cover 70 disposed in a space inside of the wall portion 68 in a radial direction form a pump chamber 72 in a space inside of the wall portion 68 in the radial direction, the pump chamber that houses a pump gear 62, with the wall portion 68, which is formed in the case cover 58, including a third inner circumferential surface 78 that is a support part rotatably supporting a rotor shaft 48 of a first rotary machine MG1 via a bearing 80, and therefore the pump cover 70 does not support an own weight of the first rotary machine MG1 due to supporting the first rotary machine MG1, or reactive force from the first rotary machine MG1. Further, a joining surface between the case cover 58 and pump cover 70 exists inside of the entire case that is formed by the case cover 58, a second case 56 and the like. Therefore, the simple configuration makes it possible to secure a sealing property in the oil pump 52.SELECTED DRAWING: Figure 2

    【課題】簡素な構造でオイルポンプにおけるシール性を確保する。【解決手段】オイルポンプ52では、壁部68を含むケースカバー58と壁部68の径方向内側の空間内に配置されたポンプカバー70とで、ポンプギヤ62を収容するポンプ室72が壁部68の径方向内側の空間内に形成されていると共に、ケースカバー58に形成された壁部68は、軸受け80を介して回転可能に第1回転機MG1のロータ軸48を支持する支持部である第3内周面78を含んでいるので、ポンプカバー70は第1回転機MG1を支持することによる第1回転機MG1の自重や第1回転機MG1からの反力を受け持たず、又、ケースカバー58とポンプカバー70との間における合せ面がケースカバー58及び第2ケース56などで形成されたケース全体の内部に存在する。よって、簡素な構造でオイルポンプ52におけるシール性を確保することができる。【選択図】図2
