PROBLEM TO BE SOLVED: To provide a linear guide device having high rigidity, high linear guide accuracy and small backlash, capable of preventing intrusion of sand, water and the like into an actuator body, and free from necessity of maintenance.SOLUTION: A linear motion body 5 is composed of a plurality of divided bodies 12a and 12b divided in the axial direction, and a plurality of guided bodies 16 kept into contact with two paired guide faces, are supported on the plurality of divided bodies 12a and 12b, thus a preload can be applied between the guide faces and the guided bodies 16. Further intrusion of external sand, water and the like into a housing 2a is prevented by applying a sealed structure to the housing 2a, and determining an internal pressure in the housing 2a to be higher than an external pressure. |
