2側的儲油室1 2 5的容積， 而且，因為返回管1 4 5係在曲柄室1 2 4内S己置於曲柄軸1 2 的下方，因此可避免曲柄箱1 4突出於下方及後方，同時可 充分確保儲油室1 2 5的容積。 另外，返回泵1 2 7係在沿著曲柄軸1 2的軸線方向配置 在偏離上述儲油室1 2 5的位置，俯視為形成為略L字狀的 上述返回管1 4 5的一端部，係液密性且可插脫地插入返回 泵1 2 7白勺泵箱1 2 9 ，另夕卜，返回管1 4 5白勺另一端部，係固 定連結於儲油室1 2 5及曲柄室12 4間白勺隔壁1 4 b，因此， 28 3 12/發明說明書(補件)/93-03/93丨0033 1 1254110 可容易將返回管1 4 5安裝於曲柄箱1 4，而且，在返回管1 4 5 的一端部側不需要組裝用零件，因此可減低零件數。 另外，吸起儲油室12 5的機油並供給引擎E的各潤滑部 的饋送泵1 2 8及上述返回泵1 2 7，係共同利用泵箱1 2 9而 同軸結合所組成，將從儲油室1 2 5吸入的機油導向饋送泵 1 2 8的吸入管1 5 7，係沿著返回管1 4 5而形成，同時，S己置 在由該返回管1 4 5所包圍的空間内，因此，可將返回泵1 2 7 及饋送泵1 2 8形成為小型構成，同時，可邊獲取儲油室1 2 5 的容積邊確保吸入管1 5 7的長度，而且可提升吸入管1 5 7 的組裝性。 又，返回管1 4 5的另一端部係在儲油室1 2 5内的前端側 下部連接於上述隔壁1 4 b，一端部連接於饋送泵1 2 8的上 述吸入管1 5 7的另一端部，係以在較返回管1 4 5的連接上 述隔壁1 4 b的連接部的更前方連通於儲油室1 2 5内下部的 方式，連接於配設於上述曲柄箱1 4的濾油器1 6 1。 因此，可縮短從儲油室1 2 5至饋送泵1 2 8的機油通路而 提高饋送泵1 2 8的泵效率，而且，因為僅以從濾油器1 6 1 至儲油室1 2 5内的機油位準的高度量，作用油壓於濾·油器 1 6 1，因此可抑制從濾、油器1 6 1經由吸入管1 5 7到達鑛送泵 1 2 8的路徑上的液壓損失。 以上說明了本發明之實施例，但本發明並不限於上述實 施例，只要在未超出申請專利範圍所記載的本發明的範 圍，便可做種種的設計變更。 例如，在上述實施例中，雖說明了將本發明應用於自動 29 3
