스포크에서의 손상을 억제하여 내구성을 향상시킨다. 트레드 링(2)과 허브(3)를 스포크(4)로 연결한 에어리스 타이어(1)이다. 스포크(4)는, 트레드측 환형부(8)와 허브측 환형부(9) 사이를 잇는 스포크판부(10)를 구비한다. 스포크판부(10)는, 허브측 환형부(9)와의 제1 접속 위치(Pa)로부터 두께(T)를 점감하는 제1 두께 점감 영역(Ya)과, 트레드측 환형부(8)와의 제2 접속 위치(Pb)로부터 두께(T)를 점감하는 제2 두께 점감 영역(Yb)과, 이들 사이에 배치되는 최소 두께 영역(Ym)을 구비한다. 제1, 제2 두께 점감 영역의 길이(L1, L2)는, 스포크판부의 길이(L0)의 0.05배 이상이다.

    [Subject Matter] To enhance durability by suppressing damage at the spoke. [Solution(s)] Airless tire 1 is structured to have a tread ring 2 and a hub 3 connected by spoke 4. The spoke 4 is structured to have a spoke plate 10 connecting a tread-side annular component 8 and a hub-side annular component 9. The spoke plate 10 is formed with a first tapered-thickness region (Ya) having thickness (T) gradually reduced from a first connecting position (Pa) bonded to the hub-side annular component 9, a second tapered-thickness region (Yb) having thickness (T) gradually reduced from a second connecting position (Pb) bonded to the tread-side annular component 8, and a minimum-thickness region (Ym) having the minimum thickness positioned between the tapered-thickness regions. The lengths (L1, L2) of the first and second tapered-thickness regions are each set to be at least 0.05 times the length (L0) of the spoke plate 10.
