Abstract:
To provide an airless tire which can high-dimensionally achieve both of ride comfort performance and durability performance.SOLUTION: An airless tire 1 comprises a tread ring 2 having a contact area 2a, a hub 3 fixed to an axle, and a spoke 4 for connection both. The spoke 4 includes a spoke plate part 5 of which width in a tire axial direction is larger than a thickness in a tire circumferential direction. The spoke plate part 5 has: a first marginal part 6 which is an end edge on the hub 3 side; a second marginal part 7 which is an end edge on the tread ring 2 side; a third marginal part 8 which is an end edge which connects the first marginal part 6 and the second marginal part 7 and has an obtuse angle θ1 with respect to the first marginal part 6; and a fourth marginal part 9 which is an end edge which connects the first marginal part 6 and the second marginal part 7 and has an acute angle θ2 with respect to the first marginal part 6, when viewed from the tire circumferential direction. The first marginal part 6 has a first thickness t1, which is a thickness in the tire circumferential direction on the third marginal part 8 side, larger than a second thickness t2 which is a thickness in the tire circumferential direction on the fourth marginal part 9 side.SELECTED DRAWING: Figure 3
