PROBLEM TO BE SOLVED: To provide a linear table allowing reduction of cost and compaction. SOLUTION: A first table 4 is constituted to be linearly driven along a base frame 1 by a ball screw shaft 2 screwed into a ball screw hole 41 passing through the table 4 and a rotating and driving means 3 for normally/reversely rotating and driving the ball screw shaft 2. A synchronous arm 62 is journalized on a first bracket 61 provided between the first table 4 and a second table 5 at a substantial center part of the base frame 1 so that the center part may be rotatable on a surface along the longitudinal direction of the ball screw shaft 2. Each of other ends of links 64 horizontally rotatably connected to each of both distal end parts of the synchronous arm 62 is rotatably connected to each of second brackets 63 of the first table 4 and the second table 5.
