PROBLEM TO BE SOLVED: To facilitate a connection between oil passages formed in the main case and the side case of a transmission case. SOLUTION: A transmission case 2 consists of a main case 3 and a side case 4. A pump oil passage 17 communicating with an oil pump 16 is formed in the main case 3. A primary pressure oil passage 19 and a line pressure oil passage 18 are formed for supplying operating pressure to each pulley 8, 9 in the side case 4. An auxiliary oil passage 20 for connecting the oil passages 17 to the oil passages 18, 19 respectively formed in both the cases 3, 4 is formed in a control valve body 6 mounted on the bottoms of both the cases 3, 4. Accordingly, these oil passages formed in both the cases 3, 4 can be connected to each other though the auxiliary oil passage 20 simply by mounting the control valve body 6 on the bottoms of both the cases 3, 4. |
