    • PROBLEM TO BE SOLVED: To compatibly maintain traction performance and lubricating performance and miniaturize a device.
      SOLUTION: A partition plate 21d is provided in a case 21 to separate a first space where a CVT 30 is disposed and a second space where a forward/backward travel switching mechanism 24 and a differential gear 28 are disposed. Bearings 42, 46 respectively supporting an input cone 34 and an output cone 36 and formed as pure rolling cylindrical roller bearings are disposed in the first space. A bearing 41 supporting one end of an input shaft 32 and formed as a conical roller bearing capable of receiving thrust force, a bearing 49 supporting an output shaft 38 and formed as a conical roller bearing capable of receiving thrust force, and a bearing 45 supporting one end of the output cone 36 are disposed in the second space and sealed by oil seals 43, 47. The first space is filled with traction oil and the second space is filled with lubricating oil.
