PROBLEM TO BE SOLVED: To provide a gimbal mechanism that can turn an object around a virtual turning axis passing through a point on an object face. SOLUTION: The gimbal mechanism is provided with at least three bearings 2a fitted to a rear side of an antenna 1, at least three rods 3, bearings 2b, 2c fitted to the rods 3, an inner face 5a fitted to the bearing 2b and having a turning shaft 4a, an outer frame 7a connected freely turnably to the inner frame 5a an inner frame 5b connected to the bearing 2c and having a turning axis X 4b, an outer frame 7b connected freely turnably connected to the inner frame 5b and having a turning axis Y 6b, a base 8 for supporting the outer frames 7a, 7b an X axis drive means for driving the frames around the X axis, a Y-axis drive means for driving the frames around the Y-axis, an X axis detection means for detecting the X-axis angle and a Y axis detection means for detecting the Y axis angle.
