PURPOSE: To easily constitute a beam vibrating type gyro measuring device used as a rate gyro or gyro scope with a small size. CONSTITUTION: This device has a resonator formed of a square base 10 and four mutually parallel beams 12a-12b integrally molded on the square base 10 and provided so as to be protruded from four corners of the square base 10. Each beam has the same resonance frequency every two directions parallel to two edges of the square base 10. Further, this device has first converters 18ab, 18ba connected to a driving circuit to vibrate each beam in a first direction vertical thereto, and second converters 18ac-18bd for detecting the vibration amplitude of each beam laid along a second direction vertical to the first direction. |
