Abstract
A blasting apparatus capable of increasing suction power to collect an abrasive without exerting any influence on processing of a work surface with the abrasive. The apparatus includes a blasting nozzle () blasting an abrasive () on a surface () of work (), a cover () including a surface () for airflow alignment parallel to the work surface and a blast hole () through which the abrasive from the nozzle passes, a nozzle case () including the cover and surrounding the nozzle, and a collecting case () covering an outer surface of the nozzle case and including a collecting passage () disposed around the nozzle case, from the passage, the abrasive being collected by suction, wherein the apparatus collects the abrasive that is blasted from the nozzle and strikes the work surface from the passage through a clearance () provided between the airflow-alignment surface and the work surface.
