PROBLEM TO BE SOLVED: To provide a non-puncture tube, in which a tube split body can be bent by a hand work, a bending step using a dedicated jig can be eliminated, and a tube can be further light weight.SOLUTION: There is provided a hollow pipe-state non-puncture tube Cwhich can be detachably attached to a toric tire rim 53, and is fitted to a toric space of a toric tire skin 51. The non-puncture tube Cis formed of plural tube split bodies Cwhich are divided along a longer direction, and a non-grounding part on an inner peripheral side which faces the tire rim 53 on each tube split body Cis partially open, in which plural ribs along a circumferential direction with a constant pitch Palong the longer direction, are formed on an opening which is continuous along the longer direction. A grounding part 1 of each tube split body Chas plural slits with a constant pitch Palong the longer direction.SELECTED DRAWING: Figure 7

    【課題】ノーパンクチューブにおいて、手作業によるチューブ分割体の曲げを可能にして、専用治具を用いた曲げ工程を不要にし、チューブの更なる軽量化を図ることである。【解決手段】円環状のタイヤリム53に着脱可能に取付けられて、同じく円環状のタイヤ外皮51の円環状空間に嵌め込まれる中空パイプ状のノーパンクチューブC1であって、前記ノーパンクチューブC1は、長手方向に沿って分割された複数のチューブ分割体C11で構成され、前記各チューブ分割体C11におけるタイヤリム53と対向する内周側の反接地部は、長手方向に沿って連続した開口部に、当該長手方向に沿って一定ピッチP1をおいて周方向に沿ったリブが多数形成されることで、部分的に開口した構造であり、前記各チューブ分割体C11の接地部1には、長手方向に沿って一定ピッチP2をおいて多数のスリットが形成された構成とする。【選択図】図7
