To provide a drive transmission unit capable of properly circulating an oil in a case.SOLUTION: A left both-side opened passage 85 extended in a lateral direction between a hydraulic pump 41L and a hydraulic motor 42L, is formed on a left-side case 72. The left both-side opened oil passage 85 is opened at its both ends. A right both-side opened oil passage 95 extended in a lateral direction between a hydraulic pump 41R and a hydraulic motor 42R is formed on a right-side case 73. The right both-side opened oil passage 95 is opened at its both ends. In a state of connecting the left-side case 72 and the right-side case 73, the left both-side opened oil passage 85 and the right both-side opened oil passage 95 are butted, and the left both-side opened oil passage 85 and the right both-side opened oil passage 95 are communicated to each other. Thus a communication oil passage 101 composed of the left both-side opened oil passage 85 and the right both-side opened oil passage 95, is formed across the left-side case 72 and the right-side case 73.SELECTED DRAWING: Figure 3

    【課題】ケース内でオイルを良好に循環させることができる、駆動伝達ユニットを提供する。【解決手段】左側ケース72には、油圧ポンプ41Lと油圧モータ42Lとの間を左右方向に延びる左両開放油路85が形成されている。左両開放油路85は、その両端が開放されている。右側ケース73には、油圧ポンプ41Rと油圧モータ42Rとの間を左右方向に延びる右両開放油路95が形成されている。右両開放油路95は、その両端が開放されている。左側ケース72と右側ケース73とが結合された状態では、左両開放油路85と右両開放油路95とが突き合わされて、左両開放油路85と右両開放油路95とが互いに連通する。これにより、左両開放油路85および右両開放油路95からなる連通油路101が左側ケース72と右側ケース73とに跨がって形成される。【選択図】図3
