Abstract
A tire frame member 17 is formed by aligning a pair of tire frame halves 17A, each including a bead portion 12, a side section 14, and a half-width crown half section 16A, with each other at the end faces of the crown half sections 16A. The tire radial direction inner side face of the crown half sections 16A includes an engagement section that engages with the outer face of a tire support member supporting the pair of tire frame halves 17A from the tire radial direction inner side, and restricts movement of the tire frame halves 17A.
Claims10
A tire comprising:
- a tire frame member that is configured from a pair of tire frame halves, each configured using a resin material and including a bead portion, a side section, and a half-width crown half section, the tire frame halves being aligned with each other and joined together at leading ends of the crown half sections;
- and
- an engagement section that is formed on a tire radial direction inner side face of each of the crown half sections, further to a tire width direction outer side than a joining portion between the crown half sections, and that engages with an outer face of a support jig that supports the pair of tire frame halves from the tire radial direction inner side during joining so as to restrict movement in a tire width direction with respect to the support jig.
A tire manufacturing apparatus comprising:
- a plurality of arm sections capable of expanding or contracting in a tire radial direction and extending toward a tire radial direction outer side;
- a tire support member that is supported from a tire radial direction inner side by leading end portions of the arm sections disposed at the tire radial direction outer side, that is segmented into a plurality of segments in a tire circumferential direction, that has an external face forming a circular ring shape around an inside periphery of a tire frame member, that contacts an inner face of the tire frame member, and that supports a pair of tire frame halves from the tire radial direction inner side;
- and
- a support engagement section that is formed on a tire radial direction outer face of the tire support member, and that engages with an engagement section formed further to a tire width direction outer side than a joining portion between the tire frame halves.
