Abstract
The purpose of the present invention is to provide a very practical nozzle body. The present invention is a nozzle body in which: a slurry-accumulating chamber (1) having a prescribed length is provided, a slurry formed of a mixture of an abrasive and a liquid being introduced into the slurry-accumulating chamber, and the slurry-accumulating chamber accumulating the slurry; an air-jetting passage (30) having a prescribed length is provided in the vicinity of the slurry-accumulating chamber (1) in a direction perpendicular to a lengthwise direction of the slurry-accumulating chamber (1); the air-jetting passage (30) and the slurry-accumulating chamber (1) are in communication through an output passage (6); pressurized air passes through the air-jetting passage (30), and the slurry is thereby outputted from the slurry-accumulating chamber (1) via the output passage (6); the slurry and the pressurized air are mixed in a mixing chamber (3); and jetting material (4) formed by mixing the pressurized air and the slurry is jetted from a slit-shaped jetting part (5).
