To provide a non-pneumatic tire including a reinforcing structure part which sufficiently supports a load of a vehicle with the structural rigidity, improves the fatigue resistance of a spoke structure with the improvement of the stress dispersibility through the load dispersion between a spoke part and a non-spoke part, disperses a shake and improves the torsional torque in the turning of the vehicle.SOLUTION: A non-pneumatic tire includes: a tread part 110 having an outer circumferential surface at which a bent pattern is formed; at least one reinforcing structure part 120 that is positioned between the outer circumferential surface of the tread part and an inner circumferential surface of the tread part so as to be inserted inside the tread part; a spoke part 130 that is formed radially around a center of the tread part and is coupled to an inner surface of the tread part; and a rim part that has a diameter smaller than a diameter of an inner circumferential surface of the spoke part and has an outer circumferential surface which is coupled to the spoke part. The reinforcing structure part has a plain weave shape surrounded by an elastomer and is wound in a circumferential direction of the tread part.SELECTED DRAWING: Figure 1

    【課題】構造的剛性で車両の荷重を十分に支え、スポーク部と非スポーク部との間の荷重分散を通じたストレス(応力)分散性の改善によりスポーク構造の耐疲労性の向上、振動の分散、車両の方向転換時のねじれトルクを向上させる補強構造部を含む非空気入りタイヤを提供する。【解決手段】外周面に屈曲されたパターンが形成されるトレッド部110と、トレッド部の内部に挿入されるようにトレッド部の外周面とトレッド部の内周面との間に位置する少なくとも1つの補強構造部120と、トレッド部の中心を基準に放射状に形成されてトレッド部の内部面と結合するスポーク部130と、スポーク部の内周面よりも小さい直径を有して外周面がスポーク部と結合するリム部と、を備え、補強構造部はエラストマーで包まれた平織(plain weave)の形で、トレッド部の周方向に巻き取られることを特徴とする。【選択図】図1
