Abstract

　ウェービング現象を抑制して超精密な運動精度を有する直動案内装置を得る。 　直動案内装置６０は、長手方向に沿って転動体転走溝６１ａが形成される軌道レール６１と、転動体転走溝６１ａに対向する負荷転動体転走溝が形成される移動ブロック６３と、転動体転走溝６１ａと負荷転動体転走溝とによって構成される負荷転走路内に転動自在に設置される複数のボールとを有することにより、移動ブロック６３が軌道レール６１の長手方向で往復運動自在とされる装置である。そして、直動案内装置６０は、ボールの直径が軌道レール６１の幅の１／１０以下となるように構成され、且つ、移動ブロック６３がＩＳＯ準拠のブロック長を有して構成されている。また、無限循環路の条数Ｌが、Ｌ＝４×Ｎ（Ｎは２以上の自然数）となるように構成されており、特に、条数Ｌが８であることが好適である。
