PROBLEM TO BE SOLVED: To obtain a support body and a pneumatic run-flat tire improving resistance property of a support part relative to the impact. SOLUTION: When large impact is applied at the time of run-flat traveling, a large load is acted on the end part side of the support part 26A from a projecting part 26A of the support part 26. However, since a reinforcing part 27 is extended from the outside end part in the tire axial direction of a flange part 26D toward the inside in the tire radial direction, the end part side of the support part 26 is reinforced and the generation of the crack from the end part side of the support part 26 is suppressed. In this way, the resistance of the support part 26 can be improved by enhancing the rigidity relative to the load at the time of impact by the reinforcing part 27. COPYRIGHT: (C)2006,JPO&NCIPI
