A sensor element (1') for gyro is disposed with its first end (25) freely vibratable in two planes (the X-Y plane and the Y-Z plane) perpendicular in relation to each other. At its end, the sensor element is fixedly retained in a structure rotatable about its longitudinal axis which is located in the above-mentioned two planes. The first end is vibratable and the vibrations are piezoelectrically detectable by means of drive and sensor electrodes respectively (26, 27, 32, respectively). The sensor element consists of or includes a tuning fork which, at the bottom, displays a transitional portion (23) which merges in an anchorage portion (7'). The electrodes cover substantial parts of the tines of the fork. Contact islets are connected to the electrodes by the intermediary of conductors (32). |
