there is provided a linear guide apparatus which , owing to the use of a gap - free braking device in a rolling guide , has a sufficiently high damping capacity . the linear guide apparatus for guiding a linear motion of a movable body along a guide rail on a fixed structure in a machine tool , includes : a rolling guide section including a rolling element for rolling on a rolling element - rolling surface of the guide rail ; and a brake section for enhancing the damping capacity of the rolling guide section , the brake section including a pair of brake shoes , having a flexible structure , for sliding on the rolling element - rolling surface of the guide rail .
