Abstract: PROBLEM TO BE SOLVED: To provide a support body and a pneumatic run-flat tire having a good fitting property to a rim. SOLUTION: The pneumatic run-flat tire is structured to make a leg portion 28 become a laminated elastic element equipped with two layers of high stiffness rubber 28A in a tire diameter direction outside and low stiffness rubber 28B in a tire diameter direction inside. Therefore, the high stiffness rubber 28A of the leg portion 28 assembled to the rim 12 ensures supporting strength. The low stiffness rubber 28B elastically deforms according to the shape of the rim 12, so that the fitting property to the rim 12 is made to be good while keeping the supporting strength.

Abstract: PROBLEM TO BE SOLVED: To efficiently lighten a shell without lowering strength and durability and to certainly supply lubricant maintaining lubricating performance to the shell and a pneumatic tire at the time of runflat travelling.
SOLUTION: A rib type hollow reinforcing part 46 is formed all over the circumference of protruded parts 30A, 30B on the cylindrical shell 26 on a support, and the lubricant L is filled in this hollow reinforcing part 46. Consequently, it is possible to lighten the shell 26 without lowering durability and strength of the shell 26. A supplying valve part of the lubricant L is provided on an outer peripheral part of the hollow reinforcing part 46, and the lubricant L in the hollow reinforcing part 46 is supplied to a contact part of the shell 26 and the pneumatic tire through the supplying valve part at the time of the runflat travelling when the shell 26 receives a load from a road surface.

Abstract: PROBLEM TO BE SOLVED: To provide a method and a device for manufacturing a metal core used for run flat tire to obtain a supporter of high dimensional accuracy.
SOLUTION: A pressing member 16 is pressed against the outer circumference of a shape-keeping roller 12 by the driving force in relation to a cylindrical metal plate 30 disposed outside the shape-keeping roller 12. Since the pressing member 16 corresponds to a recessed part 48C and expansion parts 48A and 48B on the outer circumference of the shape-keeping roller 12, the uniform plastic deformation force to form expansion parts in the metal plate 30 can be maintained, and the supporter of high dimensional accuracy can be obtained.

Abstract: PROBLEM TO BE SOLVED: To provide a support body capable of improving efficiency of tightening work of connection members attached to the vicinity of both end parts and to provide a pneumatic run-flat tire keeping predetermined resistance in the vicinity of a tightening section tightening both end parts of the support body when puncture occurs.
SOLUTION: Since end faces 44A, 44B in the longitudinal direction of the support body formed precisely according to set dimension are formed in the direction for forming an angle θ for the direction of width crossing the peripheral direction orthogonally when viewed in the radial direction, the interference of angle parts 46A, 46B and angle parts 48A, 48B is eliminated in the tightening work for tightening the connection members 34 by matching the end faces 44A, 44B mutually. Moreover, since the tightening direction of a bolt 40 and a nut 42 for tightening is inclined by an angle ϕ from the direction crossing the end faces 44A, 44B orthogonally when viewed in the radial direction, component of force in the direction crossing the tightening direction orthogonally of force generated along the end faces 44A, 44B when a vehicle performs run-flat running is suppressed, and reduction of tightening force of the bolt 40 and the nut 42 is prevented.
