PROBLEM TO BE SOLVED: To commonly use hydraulic piping for both the driving of a link cylinder for dumping and the driving of a direct-pushing cylinder for dumping. SOLUTION: When this hydraulic circuit is connected to the link cylinder 12 for dumping having a high-pressure pipe 30 and a low-pressure pipe 32, a male coupler 34M fitted to the end of a main circuit 48 is connected to the female coupler 34F of the high-pressure pipe 30, and a male coupler 36M fitted to the end of a sub circuit 50 is connected to the female coupler 36F of the low-pressure pipe 32. When the hydraulic circuit is connected to the direct cylinder 22 for dumping having only the high-pressure pipe 30, a male coupler 34F fitted to the end of a main circuit 48 is connected to the female coupler 34F of the high-pressure pipe 30, and the male coupler 36M fitted to the end of the sub circuit 50 is connected to the female coupler 36F fitted to the end of a selective flow circuit 58.
