PROBLEM TO BE SOLVED: To produce a configuration of a travel driving device for a work vehicle at low cost by reducing the number of components and reducing man-hours for assembly.SOLUTION: In the travel driving device for the work vehicle, drive power is propagated from an output shaft 20 of an engine E through a mission case 21 which shifts rotation, to rear wheels 4L and 4R while being branched to left and right by a rear axle housing 88 in which a differential mechanism is mounted. The rear axle housing 88 is divided into left and right to form left and right rear axle housing parts 88a and 88b, and a mission axle case MA1 configured by integrating the mission case 21 with one 88a of the left and right rear axle housing parts 88, is assembled with the other 88b of the rear axle housing 88 to form a power transmission section.
【課題】本発明は、作業車両の走行駆動装置の構成を部品数が少なく組立工数を少なくして廉価に生産できるようにすることを課題とする。【解決手段】エンジンEの出力軸20から回転を変速するミッションケース21を経由してデフ機構を内装したリヤアクスルハウジング88で左右に分岐して後輪4L,4Rに駆動力を伝動する作業車両の走行駆動装置において、リヤアクスルハウジング88を左右に分割して左右リヤアクスルハウジング部88a,88bにすると共に、ミッションケース21と左右リヤアクスルハウジング88の片側88aを一体構成にしたミッションアクスルケースMA1とリヤアクスルハウジング88の他方88bを組み付けて動力伝動部を構成したことを特徴とする作業車両の走行駆動装置とする。【選択図】図22
