摘要： [Problem]
To provide a canvas cleaning device that can prevent re-adhesion of stains as much as possible and also efficiently clean the canvas.
[Solution]
The canvas cleaning device 100 is provided with a base part 11 capable of sliding along a rail part 1 that extends in a width direction of a canvas K1, a cone part 13 having a cylinder shape, which is attached to the base part 11, and extends straightly, a high pressure water spraying device 13a installed inside the cone part 13, an arm part 15 that is extended and installed on the downstream side from the base part 11 and a nozzle device 16 attached to the tip of the arm part 15, and in this structure, high pressure water is sprayed onto the canvas K1 from the high pressure water spraying device 13a inside the cone part 13.
