Abstract
Provided is a non-pneumatic tire comprising: an inner cylinder 1, an outer cylinder disposed on a tire outer circumferential side of the inner cylinder 3, and a connecting body 4, wherein the connecting body has: a plurality of unit-connecting-body portions 41 and a plurality of bridges 42, each of the unit-connecting-body portions has: an inner annular part 411, a middle annular part 412, an outer connecting body part 413, each of the bridges connects tire circumferential end portions 411t of the inner annular parts adjacent to each other in the tire circumferential direction, and tire circumferential end portions 412t of the middle annular parts adjacent to each other in the tire circumferential direction are connected to each other.

A non-pneumatic tire comprising:
- an inner cylinder,
- an outer cylinder disposed on a tire outer circumferential side of the inner cylinder, and
- a connecting body that connects the inner cylinder and the outer cylinder, wherein
- the connecting body has:
- a plurality of unit-connecting-body portions arranged along a tire circumferential direction, and
- a plurality of bridges that connect the plurality of unit-connecting-body portions to each other,
- each of the unit-connecting-body portions has:
- an inner annular part having a pair of inner branches that are connected to each other on the inner cylinder and gradually move away from each other in the tire circumferential direction as moving outward in a tire radial direction, then gradually approach each other and are connected to each other,
- a middle annular part having a pair of middle branches that are connected to each other at an end portion on the tire outer circumferential side of the inner annular part and gradually move away from each other in the tire circumferential direction as moving outward in the tire radial direction, then gradually approach each other and are connected to each other, and
- an outer connecting body part having a pair of outer branches that are connected to each other at an end portion on the tire outer circumferential side of the middle annular part and gradually move away from each other in the tire circumferential direction as moving outward in the tire radial direction, and then are connected to the outer cylinder,
- each of the bridges connects tire circumferential end portions of the inner annular parts adjacent to each other in the tire circumferential direction,
- tire circumferential end portions of the middle annular parts adjacent to each other in the tire circumferential direction are connected to each other,
- each of the inner annular parts has a length in the tire radial direction longer than a length in the tire circumferential direction, and
- each of the middle annular parts has a length in the tire circumferential direction longer than a length in the tire radial direction.
