<P>PROBLEM TO BE SOLVED: To integrally provide a dust collecting mechanism at a relatively low cost and to efficiently recover dust, by using discharge of compressed air A of an air cutter. <P>SOLUTION: A cutter blade 4 rotated by being driven by a driving device 2 operated by the compressed air A is provided in a casing 3; a dust collection duct 11 is integrally provided to the circumferential face cover 32 of the casing 3; a first exhaust duct 7 and a second exhaust duct 8 are provided between a compressed air exhaust port 6 and the dust collection duct 11; and the first air discharge port 72 of the first exhaust duct 7 and the second air discharge port 82 of the second exhaust duct 8 are opened toward the downstream direction of the dust collection duct 11, and are disposed side by side along the flow direction of air in the dust collection duct 11. <P>COPYRIGHT: (C)2013,JPO&INPIT |
