- 第1部材と、第2部材と、複数の回動部材と、該回動部材同士の間に設けられる複数の間隔子と、を含む間隔子を有する伝導装置であって、
該第1部材は、第1回動溝を有し、該第2部材は、該第1回動溝と対応する第2回動溝を有し、該回動部材は、該第1回動溝と該第2回動溝の間に設けられ、
該間隔子は、設計基礎として六面体を使用し、該六面体の各表面に保持溝がそれぞれ設けられ、しかも対向する一対の該保持溝が軸対称に配置されると共に、それぞれの該保持溝が該回動部材と4点で接触するように形成され、かつ直径が該回動部材の直径の1〜0.8倍である基礎円によって、該間隔子の外縁を外切することにより、該間隔子の外縁が該基礎円に対して略球体を呈し、
該間隔子と該回動部材との間に隙間が大きくなると、該回動部材が該間隔子の一方の該保持溝から離脱し、該間隔子の回動と共に、該間隔子の他方の該保持溝と接触することにより保持されることを特徴とする、間隔子を有する伝動装置。 - 前記第1部材は、ねじロッド、リニアレール又はベアリング内部リングの何れかの1部材であり、前記第1部材に対応して、前記第2部材はナット、スライドブロック又はベアリング外部リングの何れかの1部材であることを特徴とする、請求項1に記載の間隔子を有する伝動装置。
