Abstract

A non-pneumatic tire includes an attachment body ( 11 ) attached to an axle, an inner tubular body ( 12 ) fitted onto the attachment body ( 11 ) from the outside, an outer tubular body ( 13 ) configured to surround the inner tubular body ( 12 ) from the outside in a tire radial direction, and a plurality of connecting members ( 15 ) disposed between the inner tubular body ( 12 ) and the outer tubular body ( 13 ) in a tire circumferential direction and configured to connect both of the tubular bodies ( 12 ) and ( 13 ) while maintaining relative elastic displacement therebetween, wherein at least one of an outer circumferential section of the attachment body ( 11 ) and an inner circumferential section of the inner tubular body ( 12 ) that are locked to each other is inclined throughout the circumference in the tire circumferential direction from the outside toward the inside in a tire radial direction as it goes from both of the outsides toward the inside in a tire width direction (H), and is formed in a V shape when seen in a cross-sectional view in the tire width direction (H).

First claim

What is claimed is:

1. A non-pneumatic tire comprising:
an attachment body attached to an axle;
an inner tubular body fitted onto the attachment body from the outside;
an outer tubular body configured to surround the inner tubular body from the outside in a tire radial direction; and
a plurality of connecting members disposed between the inner tubular body and the outer tubular body in a tire circumferential direction and configured to connect both of the tubular bodies while maintaining relative elastic displacement therebetween,
wherein at least one of an outer circumferential section of the attachment body and an inner circumferential section of the inner tubular body that are locked to each other is inclined throughout the circumference in the tire circumferential direction from the outside toward the inside in the tire radial direction as it goes from both of the outsides toward the inside in a tire width direction, and formed in a V shape when seen in a cross-sectional view in the tire width direction.

2. The non-pneumatic tire according to claim 1 , wherein the attachment body comprises a pair of split bodies that are split in the tire width direction.

3. The non-pneumatic tire according to claim 2 , wherein an attachment concave section is formed in one of split surfaces of the pair of split bodies, and an attachment convex section locked to the attachment concave section is formed in the second split surface.

4. The non-pneumatic tire according to claim 2 , wherein the pair of split bodies are fixed to each other by a fastening member.

5. The non-pneumatic tire according to claim 1 , wherein the outer circumferential surface of the attachment body is the outer circumferential section throughout the region in the tire width direction, and inclined from the outside toward the inside in the tire radial direction as it goes from both of the outer ends in the tire width direction inward in the tire width direction.
