PURPOSE:To provide a hydraulic structure for a working vehicle by which installation space can be reduced by supplying oil quantity efficiently to a small capacity control valve mechanism requiring a precise flow rate and a large capacity control valve mechanism by means of a small number of apparatuses. CONSTITUTION:A hydraulic structure for a working vehicle is constituted in such a way that pressure oil from a hydraulic pump 14 is divided into a control flow and an excess flow by means of a flow priority valve 27, and the control flow is supplied in series to a power steering control valve mechanism 18 and a raising and lowering link control valve mechanisms 19 and 20, and the excess flow is also flowed together with return oil from the control valve mechanisms 19 and 20, and is supplied to a control valve 28 for a hydraulic motor 24 to a sweeper. |
