There is provided a turntable drive device (1) capable of returning a position of a movable table to a predetermined direction. An outer movable table (4) is rotatably supported by rotating shafts (2a1 and 2b1), and an inner movable table (5) is rotatably supported by rotating shafts (4a and 4b) provided in the outer movable table (4). The inner movable table (5) is rotated about the rotating shafts (4a and 4b) when a connection plate (30) is linearly moved in the X direction. When a connection plate (40) is linearly moved in the Y direction, the outer movable table (4) is rotated together with the inner movable table (5) about the rotating shafts (2a1 and 2b1), based on the engagement of a rack (40c1) formed in the connection plate (40) with a toothed portion (6b) formed in the outer movable table (4). <IMAGE> |
