    摘要： According to the present invention, when a first point (P1) is set on an end edge on an outer end portion (15a) side of a coupling member (15) and a fifth point (P5) is set on an end edge on an inner end portion (15b) side of the coupling member (15), and when a distance (H1) from the fifth point (P5) to the second point (P2) along a reference straight line (RL) passing through the first point (P1) and a tire axis is set to 0.80 times a reference distance (H) from the fifth point (P5) to the first point (P1) along the reference straight line, a distance (H2) from the fifth point (P5) to the third point along the reference straight line is set to 0.65 times the reference distance (H), and a distance (H3) from the fifth point (P5) to the fourth point (P4) along the reference straight line is set to 0.30 times the reference distance (H), the third point (P3) is disposed on the other side in the tire circumferential direction of an overall inclined straight line (SL) passing through the first point (P1) and the fifth point (P5), and a horizontal distance (D2) between the second point (P2) and the third point (P3) in a perpendicular direction (D) perpendicular to the reference straight line (RL) is larger than each of a horizontal distance D1 between the first point (P1) and the second point (P2) in the perpendicular direction (D) and a horizontal distance (D4) between the fourth point (P4) and the fifth point (P5) in the perpendicular direction (D).

    摘要： Bearing structure (6) has identical bearing elements (61) in tension outside contact patch (A) with the ground and in compression in the contact patch (A). Bearing elements (61) are filamentary and are connected to radially inner face (23) of radially outer structure of revolution (2) by radially outer fabric (71) and to radially outer face (33) of radially inner structure of revolution (3) by radially inner fabric (72), respectively. Furthermore, mean surface density D of bearing elements (61) per unit area of radially outer structure of revolution (2), expressed in 1/m2, is at least equal to (S/SE)*Z/(A*Fr), where S is area, in m2, of radially inner face (23) of radially outer structure of revolution (2), SE is connecting area, in m2, of radially outer fabric (71) with radially inner face (23) of radially outer structure of revolution (2), Z is nominal radial load, in N, A is area of contact with the ground, in m2, and Fr is the force at break, in N, of bearing element (61).

    摘要： A non-pneumatic tire includes a circumferential tread having a first axial width. The tire further includes a lower annular band having a circumferential convex curved surface and a second axial width greater than the first axial width. The lower annular band is configured to deflect upon application of an axial force above a threshold axial force. The tire also includes tire structure connecting the circumferential tread to the lower annular band. The tire structure has a third axial width less than the second axial width.

    摘要： A non-pneumatic tire (1) includes an attachment body attached to an axle, a ring-shaped body (13) configured to surround the attachment body from the outside in a tire radial direction, a connecting member (15) configured to connect the attachment body and the ring-shaped body while allowing displacement therebetween, and a cylindrical tread member (16) installed outside the ring-shaped body, wherein an outer circumferential surface of the tread member has a plurality of curved surface sections (41) to (42) that are continuously formed in a tire width direction (H) with no step difference and formed in a shape protruding outward in the tire radial direction when seen in a cross-sectional view in the tire width direction, the plurality of curved surface sections have different radii of curvature in the tire width direction when seen in the cross-sectional view, and in the plurality of curved surface sections, and intermediate curved surface sections (42) disposed between a central curved surface section (41) disposed at a central portion in the tire width direction and shoulder curved surface sections (43) disposed outside in the tire width direction have a radius (R2) of curvature larger than radii of curvature (R1) and (R3) of the other curved surface sections when seen in the cross-sectional view.
