  "textContent": "[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.",
