PROBLEM TO BE SOLVED: To improve durability by suppressing the damage on a spoke.SOLUTION: An airless tire 1 couples a tread ring 2 and a hub 3 with a spoke 4. The spoke 4 is equipped with a spoke plate part 10 connecting a tread side annular portion 8 and a hub side annular portion 9. The spoke plate part 10 is equipped with a first thickness gradually decreasing area Ya gradually decreasing thickness T from a first connecting position Pa with the hub side annular portion 9; a second thickness gradually decreasing area Yb gradually decreasing the thickness T from a second connecting position Pb with the tread side annular portion 8; and a minimum thickness area Ym arranged between them. The length L1 and L2 of the first and second thickness gradually decreasing areas are longer than 0.05 times of the length L0 of the spoke plate part.SELECTED DRAWING: Figure 3

    【課題】 スポークでの損傷を抑えて耐久性を向上させる。【解決手段】 トレッドリング2とハブ3とをスポーク4にて連結したエアレスタイヤ1である。スポーク4は、トレッド側環状部8とハブ側環状部9との間を継ぐスポーク板部10を具える。スポーク板部10は、ハブ側環状部9との第1接続位置Paから厚さTを漸減する第1厚さ漸減領域Yaと、トレッド側環状部8との第2接続位置Pbから厚さTを漸減する第2厚さ漸減領域Ybと、その間に配される最小厚さ領域Ymとを具える。第1、第2厚さ漸減領域の長さL1、L2は、スポーク板部の長さL0の0.05倍以上である。【選択図】 図3
