PROBLEM TO BE SOLVED: To provide a flow control device configured compactly by laminating a plurality of blocks while reducing its piping resistance, thereby enabling smooth operation of the individual control valves constituting the flow control device. SOLUTION: A main block 64 contains a priority valve, a flow control valve 8 controlling a lift cylinder, and a direction selector valve 17 controlling a tilt cylinder, where the priority valve 3 and the flow control valve 8 are disposed in proximity to each other and the priority valve 3 is arranged close to a pump port 71. A block 64 for an attachment is disposed between the main block 65 and a cover block 63, all of which are formed into a laminated structure. The cover block 63 is provided with a tank port 66 and a high load sensing pressure port 67 and the main block 65 is provided with an input port such that these individual ports are arranged on one side of the blocks constituting the flow control device 62.
