PROBLEM TO BE SOLVED: To achieve a small-sized and highly rigid mechanism and to spatially stabilize an antenna by turning an antenna natural frequency to a high frequency for a gimbal device for antenna drive. SOLUTION: The antenna 1 is supported so as to be freely swung around a first rotary axis 2a through first rotary axis bearings 6a and 6b at two diagonal parts of a peripheral part to a movable frame 3. Also, by engaging a slide mechanism rail 4 provided on the back surface center part of the antenna 1 and provided with a circular orbit centering on the first rotary axis 2a and a slide mechanism lug 5 projected from the center part of the movable frame 3 to the antenna side, the antenna 1 is supported so as to be swung around the first rotary axis 2a.
