Abstract

一种运动引导装置(1)，运动引导装置(1)具备支承体(2)和移动体(3)，移动体(3)具有移动体主体(3a)、盖体(3b)和循环部件(4)，盖体(3b)具有第一润滑槽(3b4)，在作为润滑剂而使用润滑脂的情况下，利用由第一润滑槽(3b4)和循环部件(4)构成的润滑脂润滑路径来供给润滑剂，其中，运动引导装置(1)还具有润滑路径部件(5)，润滑路径部件(5)形成有截面积比第一润滑槽(3b4)小的第二润滑槽(5c)，在作为润滑剂而使用润滑油的情况下，利用由第一润滑槽(3b4)和第二润滑槽(5)构成的润滑油润滑路径来供给润滑剂。由此，在运动引导装置中，在利用润滑脂进行润滑时能够使润滑路径较宽，在利用润滑油进行润滑时能够使润滑路径较窄，从而能够容易地实现良好的润滑。
