<p>To provide a novel shot-blasting machine to eliminate a dead space for a cover that shuts an opening for feeding and taking out works and to open and close the cover by moving a rotary drum around an axis. The machine has a cabinet 11, a rotary drum 13 having holes, and a centrifugal shooting machine 15. The rotary drum 13 moves, within the cabinet 11, around an axis through the positions for feeding, processing, and taking out the works. The cabinet 11 comprises a cover 51 for shutting an opening 11b for feeding and taking out the works. It has a wall 59 for sealing the side of the opening 11b. The cover 51 is integrated with the rotary drum 13 to move around the axis. It has walls 51a, 51b, 51d that fit the wall 59 for sealing. Lip seals 61, 63 seal the gap between the walls 51a, 51b, 51d of the cover 51 and the wall 59 for sealing.</p> |
