Abstract

본 발명은 차축을 중심으로 일정한 폭이 있는 내, 외부원통부재 및 이들 원통부재 사이에 삽입 성형되어 접지하중을 지지하는 스포크부재 만으로 구성되는 비공기압타이어에 관한 것으로서, 본 발명에 따른 비공기압 타이어의 스포크부재는 축방향의 타이어 중심에서 보아 원뿔형 공간부가 일정 간격 뚫려지고 남은 잔여부분에 탄성물질이 채워짐으로써 구성된다.The present invention relates to a non-pneumatic tire comprising only an inner, outer cylindrical member having a predetermined width about an axle, and a spoke member inserted between these cylindrical members to support a ground load. The spoke member is constituted by the conical space portion being drilled at regular intervals as seen from the center of the tire in the axial direction and the remaining portion filled with the elastic material.
