PROBLEM TO BE SOLVED: To achieve a compact design of a transmission case by arranging each bearing hole on a center line of the case along a vertical direction in a side view. SOLUTION: The transmission case 14 for machinery for plant husbandry is constituted by a left case 34 and a right case 35 which are dividable. An input shaft 36, intermediate shafts 37 and 38, and an output shaft 40 are rotatably disposed on the left case 34 and the right case 35. Further, each bearing hole 46, 47 and 48 supporting the intermediate shafts 37 and 38 and the output shaft 40, respectively, is arranged on the approximate center line C extending along the vertical direction of the case in the side view. Thus, the intermediate shafts 37 and 38 having a relatively large gear mechanism 39 are placed in an approximate center of the case and the compact design of the transmission case 14 can be achieved. |
