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
