PROBLEM TO BE SOLVED: To provide a blasting device capable of efficiently separating and removing a coat without deteriorating a working atmosphere. SOLUTION: The device, consisting of at least one jet nozzle for jetting an ejection with a pressure air applied by a compressor and a blasting chamber forming a space region for preventing the dissipation of the ejection after jetted, is provided with moving means for moving the jet nozzle in a horizontal plate, a seal curtain for shutting the blasting chamber off an outer field and a collecting plate connected to an opening at the end of a suction duct to form a trapping space for the ejection jetted from the jet nozzle in the blasting chamber. The blasting chamber has a transparent cover for monitoring the condition of blasting the ejection.
