PROBLEM TO BE SOLVED: To provide a static pressure gas linear motion bearing mechanism which materializes miniaturization and stable positioning despite a lightweight movable body. SOLUTION: In the mechanism, a guide member 4 is arranged so as to freely movably support a movable body 2 in a guide direction X with a clearance 3 to the movable body 2 while guiding a movement of the movable body 2. The guide member 4 extended long in the guide direction X has oblique surfaces 6, 7 for receiving a load of the movable body 2 while guiding the movement of the movable body 2 through the medium of high-pressure air supplied to the clearance 3, and an intermediate support surface 8 intersecting, orthogonal in this invention, with the load direction Y of the movable body 2 between the oblique surfaces 6, 7. The oblique surfaces 6, 7 obliquely intersecting with the load direction Y of the movable body 2 so as to guide a movement of the movable body 2 through the medium of high pressure air supplied to the clearance 3 and to receive the load from the movable body 2, reversely obliquely intersects with the load direction Y of the movable body 2 with mutually equal angles θ.
