PROBLEM TO BE SOLVED: To provide a flange separation arrester showing no interference between a flange and a structure around the flange.SOLUTION: This invention relates to a flange separation arrester 10 including a holding member 11 for holding a pair of flanges 3d, 4d having walls 11b, 11c vertically set at both sides of a base bottom part 11a in which an inner bottom surface 11d of the base bottom part 11a is arranged to oppositely face against outer peripheral surfaces of the pair of flanges 3d, 4d so as to prevent the pair of flanges 3d, 4d from being separated from each other. At least one wall of the holding member 11 comprises a rotating member 14; a forward/backward motion member 15 performing forward/backward motion through rotation of the rotating member 14; and a direction changing member 12 for generating displacement in a direction different from the forward/backward direction of the forward/backward motion member 15.SELECTED DRAWING: Figure 4 |
