For example, as shown in FIG. 6, the core a is supported by a pair of left and right elastic rings b disposed on both sides of the lower end of the core a. The two elastic ring members b each include a horizontal main portion b1 that receives the lower surface of the core a, and an elastic deformation portion b2 that swells at the outer end thereof and is compressed between the tire bead c and the core a. And the lower end of the core a is fitted and supported between the elastically deforming portions b2 by the narrow pressure.

両側に配される。However, adjustment of the internal pressure from the tire valve (filling with air) is required for the elastic ring b.
In order to perform the above, the valve holes f are disposed on both sides with a distance d from which the valve holes f can be exposed.

Finally, there arises a problem that the interval d eventually disappears and adjustment of the internal pressure becomes impossible.

中子の固定をより強固に行いうる。The pair of elastic rings extend the main portions inserted between the tire core and the rim, respectively, and form, at the inner ends thereof, butting surfaces which abut against each other. Therefore, the receiving area to the tire core increases, and the load supporting ability can be sufficiently exhibited by preventing the core from bending and deforming. Also, the stability of the insertion is increased and the butting surfaces interfere with each other, so that the displacement and loosening of the elastic ring body are suppressed,
The core can be fixed more firmly.

In particular, since the upper and lower cutouts are continuous in the circumferential direction, the valve hole and the air passage can communicate with each other regardless of the relative positions of the rim and the core in the circumferential direction at the time of assembly. An air flow path for adjusting the internal pressure can be formed without impairment. The locking portions provided on the abutting surfaces prevent the left and right elastic ring bodies from shifting in the circumferential direction, thereby ensuring the formation of the conducting portion having a large opening area.
