An object is to provide a linear motion guide device 1 which has a high rigidity, a good linear motion guiding accuracy, and as little rattling as possible. The linear motion guide device 1 does not allow sand, water or other contaminants from entering its actuator main body, and features low maintenance requirement. A linear motion member 5 is constituted by a plurality of axially divided segments (12a through 12c). Each of these segments (12a through 12c) supports a plurality of guided members 16 which make contact with two, mutually paired guide surfaces 15. A preload can be applied between the guide surfaces 15 and the guided member 16. The housing 2 has a sealed structure, with a pressure inside the housing 2 higher than an external pressure, for preventing external sand and water from entering the housing 2. |
