A liquid diluting device, with a small and simple structure, is capable of reliably sealing and simply changing dilution concentration. Diluent passages are formed in a first body, and a connecting passage for introducing special liquid connects to these diluent passages. A cylindrical dial covering an opening section of the connecting passage is rotatably provided on an outer section of the first body, a plurality of jets passing through from the inside to the outside are formed in conjunction with this cylindrical dial, and the diameters of the plurality of jets are different. A liquid supply passage is set at a position opposite the connecting passage, so that the cylindrical dial is sandwiched between the liquid supply passage and the connecting passage, and the connecting passage and the liquid supply passage are connected by a jet having a diameter matching the dilution factor to introduce special liquid from the liquid supply passage to one of the diluent passages. In this way, by rotatably attaching the cylindrical dial in which the plurality of jets are formed to the first body, it is possible to have a small and simple structure, and also to easily change the dilution factor by merely turning the dial.
