Abstract

　小型化を図りつつも固定側部材に対する移動側部材のストローク量の増大を図ることができ、しかも容易に且つ低コストで生産することが可能な二段式スライドユニットであり、固定側レール(1)と、多数のボール(4)を介して前記固定側レール(1)に対して移動自在に組付けられた中間支持部材(3)と、多数のボール(4)を介して前記中間支持部材(3)に対して移動自在に組付けられた移動側レール(2)とから構成され、前記固定側レール(1)及び移動側レール(2)は断面略矩形状に形成されると共に両側面には長手方向に沿って１条ずつのボール転走溝(10,20)が形成される一方、前記中間支持部材(3)には前記固定側レール(1)が遊嵌する第１の凹部(33)及び前記移動側レール(2)が遊嵌する第２の凹部(34)が互いに平行に形成されると共に、各凹部の内壁には前記固定側レール(1)又は移動側レール(2)のボール転走溝(10,20)を転動するボール(4)が無限循環するトラック溝(40)を形成した。
