- the above-mentioned core has a volume of about 0.8 L (L: liter) per projection (part between notches). If it is still made of a material with a density of 1, it will be about 0.8 kg. In the whole, it will be 10 k.g only at the protrusions, which is too heavy. Therefore, the weight was reduced by using resin or reinforced resin (for example, glass fiber mixed resin; density 1.5 to 1.7), and making the protrusions hollow to reduce the volume. -The run flat system is targeted to withstand a puncture of 200 km. When punctured, the core must fully support the vehicle mass.
- the core 10 is composed of a plurality of blocks (also referred to as “core blocks”) 15 produced by injection molding of resin or reinforced resin.
- Each block 15 has a shape that can withstand vertical and vertical loads, front and rear, and left and right loads and can be easily manufactured by resin injection molding.
- the block 15 has a box shape in which the upper surface 13 and the side surface are closed and the lower surface 14 is open, and has a plate inside the box 11 extending in the wheel circumferential direction and the Z or wheel axial direction ( For example, insert a grid-like) reinforcing plate (even with ribs) 1 2.
- the up-down direction of the core corresponds to the wheel radial direction when the core is mounted on the wheel
- the upper surface of the core corresponds to the outer side in the wheel radial direction

It consists of a mechanism that changes between “when loose” in FIG. 16A and “when tightened” in FIG. 16B.
- the intermediate link 29 connects the left and right belts 19 or the connecting part 17 of the wires 20 with rods (rods 24 in Fig. 14), and
- the head of the wheel may be directed outward in the wheel axial direction so that the belt and wire can be tightened (rotation of the rod) from the outer side in the wheel axial direction.
