RIM, ASSEMBLY OF TIRE AND RIM, AND MANUFACTURING METHOD FOR ASSEMBLY OF TIRE AND RIM

摘要

PROBLEM TO BE SOLVED: To easily attach/detach a tire having a tube body formed by a thermoplastic elastomer relative to a rim without using a rim-assembling machine. SOLUTION: In the rim 10, the tire 20 provided with the tube body 21 formed by the thermoplastic elastomer and a tread 22 provided on an outer side of the tube body 21 is attached to an outer peripheral part 12. Both end parts in a tire width direction H on the outer peripheral part 12 are made to support projection parts 12b extending in a tire radial direction and supporting the tube body 21 from an outer side in the tire width direction H, and rim 10 is constituted so as to be dividable to a first division rim 14 and a second division rim 15. At least the first division rim 14 of both the division rims 14, 15 is formed such that an outer diameter at one side end edge 14a positioned with a division surface B of both the end edges in the tire width direction H becomes smaller than an outer diameter at the other side end edge 14b.
