Abstract
The linear guide 10 includes a track rail 20, a movable block 30, and rollers 40 arranged between the track rail 20 and the movable block 30 and capable of endlessly circulating. A section of the linear guide 10 including an axis line of the rollers 40 and taken vertically across an unloaded roller rolling path 50 or a direction change path 60, the unloaded roller rolling path 50 or the direction change path 60 includes attitude support portions 55 that support an attitude of the rollers 40 rolling on the unloaded roller rolling path 50 or the direction change path 60, and space portions 54, 54a, and 54b that release a lubricant present inside the unloaded roller rolling path 50 or the direction change path 60. With such configuration, a smooth guide motion of a motion guide device is achieved unaffected by the lubricant in an unloaded circulation path.
