PROBLEM TO BE SOLVED: To provide a dilution device capable of securing an adequate discharge pressure even when a discharge port of dilution liquid is disposed on a position higher than the dilution device by using only a tap water pressure as a power without using other power such as electricity even for high-viscosity fluid such as chemicals of detergent, etc. and capable of preparing the dilution liquid of which the dilution rate is made substantially constant without using special sensors concerning water quantity and dilution concentration. SOLUTION: The dilution device is provided with: a closed flow path constituted by connecting a feed-water port of tap water, a water path A, a water turbine, a water path B, a check valve, a water path C and a discharge port of dilution liquid in the order; a crank mechanism which is connected with a rotation shaft of the water turbine and converts a rotating motion of the water turbine driven by tap water flowing through the flow path into a linear reciprocating motion; and a diaphragm pump comprising a diaphragm of performing a linear reciprocating motion by the crank mechanism, a check valve of chemical suction side and a check valve of chemical discharge side, wherein a discharge port of chemicals from the check valve of chemical discharge side is connected to a middle part of the water path C via a chemical pipe D.
