PROBLEM TO BE SOLVED: To realize a solution diluting device in which the variation of a dilution scale factor of a solution can be made small.SOLUTION: When tap water is supplied to a second space 22 from a solution supply port 11, a moving member 24 is moved by the pressure, a herbicide housed in a first space 21 is pushed out, and the pushed-out herbicide is flowed into a dilution mechanism 50 through a solution flowing-out pipe 23. The dilution mechanism 50 mixes the flowed-in herbicide and the tap water flowed out from the second space 22, and the herbicide of a dilution scale factor set by a dial 41 is discharged to a spray mechanism 30. As there is no possibility that a moving speed changes during moving because the moving member 24 is moved by two mechanisms of the inner wall of a container 20 and the solution flowing-out pipe 23, the variation in the dilution scale factor of the herbicide is small.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】液剤の希釈倍率の変動を小さくすることができる液剤希釈装置を実現する。【解決手段】水道水を溶媒供給口11から第2の空間22に供給すると、その圧力によって移動部材24が移動し、第1の空間21に収容されている除草剤が押し出され、その押し出された除草剤が液剤流出管23を通って希釈機構50に流入する。希釈機構50は、流入した除草剤と第2の空間22から流出した水道水とを混合し、ダイヤル41によって設定された希釈倍率の除草剤を散布機構30へ吐出する。移動部材24は容器20の内壁面および液剤流出管23の2つの構造により移動するため移動途中で移動速度が変動するおそれがないので除草剤の希釈率の変動が小さい。【選択図】図1
