To provide an inexpensive and lightweight liquid spraying device.SOLUTION: In a tank 1, a bag body 3 having a volume substantially half that of the tank and having one end 3a open is provided, and the bag body is provided with an opening edge 3a So that the bag can freely be reversed in the inside of the tank. The tank is provided with a liquid injection port 5, and the pair of end portions 1 b, 1 c of the tank are provided with a first insertion hole 9 a and a second insertion hole 9 b penetrating the tank inwardly and outwardly, and face the bottom portion 3 b of the bag body A water pipe or an engine exhaust gas pipe 13 is connected to the first insertion hole and a liquid spray pipe 17 is connected to the second insertion hole. Liquid is injected into the tank from the liquid injection port, and is introduced into the bottom of the bag The tap water or the engine exhaust gas is pressed into the tank through the first insertion hole and the bottom portion of the bag body is pressed in a direction approaching the second insertion hole to which the liquid spray pipe is connected, Spray the liquid from the liquid spray pipe.BACKGROUND OF THE INVENTION【課題】安価で軽量の液体散布装置を提供する。【解決手段】タンク1には該タンクの略二分の一の容積を有し、かつ、一端3aを開口した袋体3を内設し、該袋体は、当該一端の開口縁3a’をタンクの中央部1a内面に該袋体が該タンク内にて表裏反転自在になるように密着させる。タンクには液体注入口5を備えさせ、タンクの一対の端部1b、1cにはタンクを内外に貫く第一挿通孔9aと第二挿通孔9bとを備えさせ、袋体の底部3bに臨む第一挿通孔には水道管又はエンジン排気ガス管13を接続し、第二挿通孔には液体散布管17を接続し、該タンクには液体を液体注入口より注入し、袋体の底部に臨む第一挿通孔を介して水道水又はエンジン排気ガスをタンク内に圧入して袋体の底部を液体散布管が接続された第二挿通孔に接近する方向に押圧させることにより、タンク内の液体を液体散布管より散布する。【選択図】図1
