PROBLEM TO BE SOLVED: To provide an asphalt solution spraying device capable of pulling in and housing an asphalt solution spraying pipe arranged in a rear end surface lower part of a spraying car onto a loading space of the spraying car at unused time. SOLUTION: A support arm 6 is pivotally fixed to a rear surface of a solution tank 1 mounted on the loading space of the spraying car so as to freely rise and fall and rotate. A guide cylinder 7 is integrally arranged on the tip of this support arm 6. A sliding arm 8 for slidingly moving in the right-angled direction to the support arm 6 is inserted into and supported by this guide cylinder 7. The spraying pipe 3 is suspended and supported on the tip of this sliding arm 8. The support arm 6 is brought down backward from a rising state, and the sliding arm 8 is arranged along a rear end surface of the spraying car. The spraying pipe 3 of the lower end is arranged in a spraying position. The support arm 6 is erected, and the sliding arm 8 is slidingly moved forward so that the spraying pipe 3 can be housed on a rear end part of the loading space.
