    摘要： A pneumatic tire (1) includes an inner cylinder (6), an outer cylinder (4), and a connecting member (3), in which the outer cylinder (4) and the connecting member (3) are formed to be elastically deformable, and the thickness of the thickest part of the outer cylinder is thicker than the thickness of the thickest part of the connecting member. When the outer cylinder is pushed by a protrusion, and deformed toward the inside in a tire radial direction, at least a part of the connecting member which is positioned between the protrusion and the inner cylinder and other connecting members adjacent to the connecting member in the tire circumferential direction abut each other. When the non-pneumatic tire (1) is mounted on a vehicle and travels on a flat contact plane, a gap is secured between the connecting member positioned between the ground plane and the inner cylinder and other connecting members adjacent to the connecting member in the tire circumferential direction.

    摘要： In the present invention, a non-pneumatic tire (1) includes an inner cylinder attachable to an axle shaft, an outer cylinder (4) configured to surround the inner cylinder from the outside in a tire radial direction, a linking member (3) configured to link the inner cylinder to the outer cylinder (4), and a tread member (5) externally fitted onto the outer cylinder (4). The outer cylinder (4) includes an outer circumferential section (41) positioned on a tire equatorial line, side sections (42) positioned on both sides in a tire width direction with respect to the outer circumferential section (41), and a shoulder section (43) configured to connect the outer circumferential section (41) to the side sections (42). The tread member (5) covers the outer circumferential section (41), the side sections (42), and the shoulder section (43), and the shoulder section (43) is chamfered.

    摘要： A non-pneumatic tire (1) comprising: a mounting body (11) that is mounted on a vehicle axle; a ring component (14) that is provided with an inner cylindrical body (12) that is fitted onto the outside of the mounting body (11), and an outer cylindrical body (13) that encircles the inner cylindrical body (12) from the outside in the radial direction of the tire (1); and a plurality of linking components (15) that are lined up along the circumferential direction of the tire between the inner cylindrical body (12) and the outer cylindrical body (13), and that link together these two cylindrical bodies (12, 13) such that they can be elastically displaced relative to each other, wherein the ring component (14) and the plurality of linking components (15) are formed integrally as a single unit; a plurality of protruding bar portions (12a) that protrude inwards in the tire radial direction are provided at a distance from each other in the tire circumferential direction on the inner circumferential surface of the inner cylindrical body (12) configured to extend for the entire length of this inner circumferential surface in the tire transverse direction; a plurality of key groove portions (18a) are formed in the outer circumferential surface of the outer ring portion (18) of the mounting body (11) at a distance from each other in the tire circumferential direction configured to be recessed towards the inner side in the tire radial direction and configured to also extend in the tire transverse direction; and a plurality of hole rows (18c) that are formed at a distance from each other in the tire transverse direction by creating a plurality of weight reduction holes that penetrate the outer ring portion (18) in the tire radial direction are formed apart from each other in the tire circumferential direction in the mounting body (11) and are located between mutually adjacent key groove portions (18a) in the tire circumferential direction.
