A motion guide device is provided, which is able to not only lubricate rolling-element rolling surfaces with the use of a technique totally different from conventional lubricating techniques but also maintain a lubricating capability over a long period of time. The motion guide device for use in the vacuum environment a track member () having a rolling-element rolling part (), a moving member () having a rolling-element circulation passage containing a loaded rolling-element rolling part () facing the rolling-element rolling part () and being movable relatively to the track member (), a plurality of rolling elements () placed in along the rolling-element circulation passage, and a lubricant storing member storing lubricant, which member is attached to the moving member () without contacting the track member (). The lubricant storing member is exposed in a space formed between the track member () and the moving member. The vaporized lubricant reaches the rolling-element rolling part (), loaded rolling-element rolling part (), and rolling elements (), so that these parts and elements can be lubricated.
