Zusammenfassung:	PROBLEM TO BE SOLVED: To simplify and shorten a hydraulic system from a hydraulic power source to each hydraulic device of a work vehicle such as a tractor as much as possible.SOLUTION: A work vehicle 1 includes an engine 5 mounted on a travelling machine body 2 which is supported by travelling parts 3, 4, and a transmission case 17 incorporating a hydraulic non-stage transmission 500. A PTO transmission mechanism 505 and a PTO hydraulic clutch 590 are arranged in the transmission case 17. PTO valves 627, 628 for operating the PTO hydraulic clutch 590 are included. The PTO valves 627, 628 are arranged in positions overlapping the PTO hydraulic clutch 590 in a side view on right and left one side surfaces of the transmission case 17.SELECTED DRAWING: Figure 15 【課題】トラクタのような作業車両において、油圧源から各油圧装置に至る油圧系統をできるだけ簡単且つ短くする。【解決手段】本願発明の作業車両１は、走行部３，４で支持する走行機体２に搭載したエンジン５と、油圧無段変速機５００を内蔵したミッションケース１７とを備える。ミッションケース１７内には、ＰＴＯ変速機構５０５とＰＴＯ油圧クラッチ５９０とを配置する。ＰＴＯ油圧クラッチ５９０を作動させるＰＴＯバルブ６２７，６２８を備える。ミッションケース１７の左右一側面には、側面視でＰＴＯ油圧クラッチ５９０と重複する位置に、ＰＴＯバルブ６２７，６２８を配置する。【選択図】図１５
