Abstract

スライダ本体(4)に一対のエンドプレート(5)を組み付けて転動体(3)の無限循環路(30)を構成するにあたり、エンドプレート(5)を薄く形成してスライドブロック(2)の長尺化を回避すると共に、エンドプレート(5)及びスライダ本体(4)の構成の簡略化を図り、簡易に且つ低コストで生産することが可能な直線案内装置であり、前記エンドプレート(5)に具備された方向転換溝路(33)は、前記スライダ本体(4)の負荷通路(31)又は無負荷通路(32)に連続する一対の導入曲線部(A)と、これら一対の導入曲線部(A)を滑らかに連結する中央転走部(B)とから構成され、前記導入曲線部(A)はその曲率中心が前記スライダ本体(4)の端面(43)に対する負荷通路(31)又は無負荷通路(32)の開口縁に位置し、且つ、曲率半径が転動体直径の約１／２である一方、前記中央転走部(B)の曲率半径は前記導入曲線部(A)の曲率半径よりも大きく設定されている。
