The present invention relates to an airless tire, which comprises: an inner ring which has an axle coupled to an inner circumference and is made of a rigid material which is not deformed by external force; an outer ring which has a tread member coupled to an outer circumference and is made of a rigid material which is not deformed by external force; and an elastic spoke which is installed between the inner ring and the outer ring to connect the inner and outer rings as one, and is made of a stretchable elastic material to support a load acting on the tire with tensile elasticity. The elastic spoke includes: a plurality of main spokes which are arranged radially between the inner ring and the outer ring and bent at an angle at which both ends are respectively connected to corresponding joint rings, and are arranged alternately so that bent edges face in opposite directions; and a plurality of auxiliary spokes which interconnects adjacent outer edges of two neighboring main spokes among the plurality of main spokes in a circumferential direction. The present invention can improve driving performance.

    본 발명은 에어리스 타이어에 관한 것으로, 내주에 차축이 결합되고, 외력에 의해 변형되지 않는 강성 재질의 이너링(inner ring); 외주에 트레드 부재가 결합되고, 외력에 의해 변형되지 않는 강성 재질의 아우터링(outer ring); 및 이너링과 아우터링 사이에 설치되어 양자를 일체적으로 연결하고, 신축 가능한 탄성재질로 구성되어서 타이어에 작용하는 하중을 인장 탄성으로 지지하는 탄성 스포크;를 포함하고, 탄성 스포크는, 이너링과 아우터링 사이에 방사상으로 배치되어 양단이 대응하는 접합링들에 각각 연결되는 앵글(angle) 상으로 절곡 구성되고, 절곡된 모서리가 서로 반대 방향을 향하도록 교번적으로 배치되는 다수의 메인 스포크; 및 다수의 메인 스포크들 중 이웃하는 두 메인 스포크의 근접하는 모서리 외측을 원주방향으로 상호 연결하는 다수의 보조 스포크;를 포함한다.
