Abstract
Abstract A non-pneumatic tire with spokes easily mountable on and dismountable from a wheel. In the non-pneumatic tire ( 1 ), a spoke structure ( 10 ) including an annular outer peripheral member ( 3 ) and an inner peripheral member ( 5 ) connected to each other by a plurality of spokes ( 4 ) is joined to the inner peripheral side of a tread ring ( 2 ). The non-pneumatic tire is characterized in that the inner peripheral member ( 5 ) is divided into independent members ( 51 ) in the circumferential direction of the tire.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
56 words
1 . A non-pneumatic tire comprising a spoke structure including an annular outer peripheral member and an inner peripheral member connected to each other by a plurality of spokes joined to the inner circumferential side of a tread ring, wherein said inner peripheral member is divided into independent members in the circumferential direction of the tire.
Claim 2
Dependent Claim
56 words
1 . A non-pneumatic tire comprising a spoke structure including an annular outer peripheral member and an inner peripheral member connected to each other by a plurality of spokes joined to the inner circumferential side of a tread ring, wherein said inner peripheral member is divided into independent members in the circumferential direction of the tire.
Claim 3
Dependent Claim
24 words
2 . The non-pneumatic tire according to claim 1 , wherein a space lies between said independent members that are adjacent to each other.
Claim 4
Dependent Claim
32 words
3 . The non-pneumatic tire according to claim 1 , wherein lengths of said independent members are the same with each other or periodically different in the circumferential direction of the tire.
Claim 5
Dependent Claim

4 . The non-pneumatic tire according to claim 1 , wherein a connecting means that continues in the circumferential direction of the tire is hung over said independent members.
Claim 6
Dependent Claim
35 words
5 . The non-pneumatic tire according to claim 1 , wherein said spoke is formed in a blade shape, and the face direction of the blade is arranged in the width direction of the tire.
Claim 7
Dependent Claim
35 words
6 . The non-pneumatic tire according to claim 1 , wherein said spoke is formed in a blade shape, and the face direction of the blade is arranged in the circumferential direction of the tire.
Claim 8
Dependent Claim
