Rotary gyroscope

A rotary gyroscope (10) includes a base plate (1), an intermediate structure (3), including a driven element (33) floating over the base plate as supported by a driving supporter (34) radially extending therefrom, the driven element (33) performing an oscillating motion (63) with respect to a first axis (Z), which is vertical to a center plane thereof, a driving electrode (35) driving the driven element (33), and a sensing element (31) disposed in the driven element (33) and connected to the driven element (33) by a sensing connector (32) to oscillate together with the driven element (33) and concurrently to perform a sensing motion (62) with respect to a third axis (Y), which is vertical to the first axis (Z) and any second axis (X), which is parallel to a center plane, due to a Coriolis force when an angular velocity (61) is inputted from the second axis (X), and a cover (4) covering the intermediate structure (3) and having a sensing electrode (41) to detect the sensing motion (62) of the sensing element (31).
