PURPOSE:To avoid projecting a power take-in shaft, a travelling shaft and a power take-off shaft in the direction of the axle, by arranging the above-mentioned shafts in substantial parallel with a plane which is orthogonal to the center line of the axle. CONSTITUTION:An axle 2 is arranged to pierce through the lower section of a mission casing 1, perpendicular to or substantially perpendicular to the mating surface of the mission casing 1. Slightly above this axle 2, a PTO shaft 3 is arranged in a plane which is orthogonal to the center line of the axle 2. A power take-in shaft 4 having its axis common to the PTO shaft 3 arranged to pierce through the mission casing, evading the mating surface of the mission casing. With this arrangement, both PTO shaft 3 and power take-in shaft 4 are arranged in parallel with the axle 2 so that the travelling speed change gear unit may be made narrow. |
