The invention relates to a vibrating structure gyro produced by micromachining in a flat thin plate. It comprises two symmetrical mobile assemblies (30, 10, 50; 30 ', 10', 50 ') coupled by a coupling structure (20, 20', 22) connecting these two assemblies to allow a transfer t of mechanical energy of vibration between them, each mobile assembly comprising three mobile assemblies (30, 10, 50) a first inertial mobile element (50) and intended to vibrate in two orthogonal directions Ox and O y in the plane of the plate, a second mobile element ( 10) for vibrating along Oy and connected to the first movable member (50) and to fixed anchoring zones (34, 36) by first connecting means (12, 14, 16, 18, 60, 62, 6). 4, 66) which allow the transmission to the second mobile element of the vibration movement of the first mobile element according to Oy without allowing a movement of the second element in the Ox direction, a third mobile element (30) intended to vibrate along Oy and connected to the second movable member and fixed anchoring zones (34, 36), second connection means (52, 54, 56, 58, 40, 42, 44, 46) which permit the transmission in phase opposition to the third mobile element of the vibration movement of the second movable element according to Oy.
