A non-pneumatic tire comprising: an attachment body attachable to an axle; a ring-shaped body configured to surround the attachment body from the outside in a tire radial direction; and a plurality of connecting members disposed between the attachment body and the ring-shaped body in a tire circumferential direction and configured to displaceably connect the attachment body and the ring-shaped body; wherein in the plurality of connecting members, a plurality of curved sections (21d, 21e, 21f, 22d, 22e, 22f), which include first curved sections (21d, 22d), second curved sections (21e, 22e) and third curved sections (21f, 22f), curved in the tire circumferential direction are formed at intermediate portions (21c, 22c) disposed between first end sections (21a, 22a) connected to the ring-shaped body and second end sections (21b, 22b) connected to the attachment body in a direction in which the connecting members extend in a side view of the tire when the tire is seen from the tire width direction in a state in which no compressive load is applied in the tire radial direction, among the plurality of curved sections (21d, 21e, 21f, 22d, 22e, 22f), the second curved sections (21e, 22e) joined to the first end sections (21a, 22a) have a smaller radius of curvature than the first and third curved sections (21d, 21f, 22d, 22f) disposed closer to the second end sections (21b, 22b) than the second curved sections (21e, 22e) joined to the first end sections (21a, 22a) in a state in which no compressive load is applied in the tire radial direction, characterised in that when the tire comes in contact with the ground, the plurality of connecting members are deformed by a compressive load in the tire radial direction, and the attachment body and the ring-shaped body are deformed in the tire radial direction, among the plurality of connecting members, the connecting members disposed between the ground surface with which the tire comes in contact and the attachment body abut other connecting members neighboring in the tire circumferential direction, and the connecting members neighboring in the tire circumferential direction in the plurality of connecting members abut each other via abutting portions in elongated state parallel to the ground surface, and at least some of the abutting portions overlap parallel to the ground surface in a side view of the tire when the tire is seen from a tire width direction. an attachment body attachable to an axle; a ring-shaped body configured to surround the attachment body from the outside in a tire radial direction; and a plurality of connecting members disposed between the attachment body and the ring-shaped body in a tire circumferential direction and configured to displaceably connect the attachment body and the ring-shaped body; wherein in the plurality of connecting members, a plurality of curved sections (21d, 21e, 21f, 22d, 22e, 22f), which include first curved sections (21d, 22d), second curved sections (21e, 22e) and third curved sections (21f, 22f), curved in the tire circumferential direction are formed at intermediate portions (21c, 22c) disposed between first end sections (21a, 22a) connected to the ring-shaped body and second end sections (21b, 22b) connected to the attachment body in a direction in which the connecting members extend in a side view of the tire when the tire is seen from the tire width direction in a state in which no compressive load is applied in the tire radial direction, among the plurality of curved sections (21d, 21e, 21f, 22d, 22e, 22f), the second curved sections (21e, 22e) joined to the first end sections (21a, 22a) have a smaller radius of curvature than the first and third curved sections (21d, 21f, 22d, 22f) disposed closer to the second end sections (21b, 22b) than the second curved sections (21e, 22e) joined to the first end sections (21a, 22a) in a state in which no compressive load is applied in the tire radial direction, characterised in that when the tire comes in contact with the ground, the plurality of connecting members are deformed by a compressive load in the tire radial direction, and the attachment body and the ring-shaped body are deformed in the tire radial direction, among the plurality of connecting members, the connecting members disposed between the ground surface with which the tire comes in contact and the attachment body abut other connecting members neighboring in the tire circumferential direction, and the connecting members neighboring in the tire circumferential direction in the plurality of connecting members abut each other via abutting portions in elongated state parallel to the ground surface, and at least some of the abutting portions overlap parallel to the ground surface in a side view of the tire when the tire is seen from a tire width direction.
