Beschreibung
Zusammenfassung:	To provide a service vehicle in which an increase in a manufacturing cost can be easily curbed.SOLUTION: A service vehicle comprises: a hydrostatic continuously variable transmission 2 which has a hydraulic circuit 20; a first oil passage 21 where oil flows therethrough when supplied from an oil tank 7 to the hydraulic circuit 20; a second oil passage 22 where the oil flows therethrough when returned from the hydraulic circuit 20 to the oil tank 7; a third oil passage 23 where the oil flows therethrough when supplied from the oil tank 7 to a hydraulic actuator M; and a fourth oil passage 24 where the oil flows therethrough when returned from the hydraulic actuator M to the oil tank 7. A cooling device 72 cooling the oil is installed on the fourth oil passage 24. The oil supplied from the oil tank 7 to the hydraulic circuit 20 is returned from the hydraulic circuit 20 to the oil tank 7. The oil supplied from the oil tank 7 to the hydraulic actuator M is returned from the hydraulic actuator M to the oil tank 7 through the cooling device 72.SELECTED DRAWING: Figure 3 【課題】製造コストの増大を抑制しやすい作業車を提供する。【解決手段】油圧回路２０を有する静油圧式無段変速機２と、オイルタンク７から油圧回路２０へ供給されるオイルが流れる第１油路２１と、油圧回路２０からオイルタンク７へ戻るオイルが流れる第２油路２２と、オイルタンク７から油圧アクチュエータＭへ供給されるオイルが流れる第３油路２３と、油圧アクチュエータＭからオイルタンク７へ戻るオイルが流れる第４油路２４と、を備え、第４油路２４に、オイルを冷却する冷却装置７２が設けられており、オイルタンク７から油圧回路２０へ供給されたオイルは、油圧回路２０からオイルタンク７へ戻り、オイルタンク７から油圧アクチュエータＭへ供給されたオイルは、油圧アクチュエータＭから冷却装置７２を通ってオイルタンク７へ戻る。【選択図】図３
