Abstract: PURPOSE: To provide a linear guide device and a plane guide device smoothly operating even in the use at high load by forming pinions on the both end parts of many rollers coaxially with the rollers, and forming racks meshing with the pinions on the outside parts of a roller rolling face. CONSTITUTION: Pinions 7 on both ends of a roller 3 meshing with racks 8 are equally rotated by movement of a movable stand 2, and the roller 3 is moved by the same distance at both ends. All the rollers 3 are respectively moved by the same distance, and hence spaces of the rollers 3 are not changed. Because the rolling quantity of the roller 3 is the same in any movement, forward movement and backward movement, of the movable stand 2, the rollers 3 are not partial to one side of the front and rear directions of roller rolling faces 4, 5, but always positioned on the nearly center of the roller rolling faces 4, 5. Further, even when the size of the roller is enlarged, parallelism of the rollers can be maintained so as to prevent generation of slant of the rollers, and even when the space of the rollers is reduced, the rollers can be prevented from contacting with each other.
