摘要： PROBLEM TO BE SOLVED: To prevent a torsional force from being generated within an oscillator by the Coriolis force generated according to rotation, and perform a highly efficient detection free from vibration leakage by arranging four parallel vibrating pieces one-side ends of which are commonly fixed so that the adjacent pieces have a substantially equal space. SOLUTION: An oscillator 1 is formed of a square pole fixing base 10, and four vibrating plates 2-5 fixed to the side surfaces thereof by non-elastic solder glass. The vibrating plates 2-5 are formed of thin monocrystal bases of quartz, and have the same plane form in which slender vibrating pieces 6-9 are protruded from one-side short edges of rectangular base parts, respectively. The vibrating pieces 6-9 are arranged so as to have the same distance from a virtual axis parallel to a rotating shaft having a detected angle speed and an equal space, and an equal space between the adjacent ones. An exciting circuit excites the vibrating pieces 6-9 so that each is vibrated in the same direction with the reverse phase to the vibrating piece opposed thereto, and in the orthogonal direction,to the vibrating piece adjacent thereto. Thus, no torsional force is generated in the commonly fixed part of the vibrating pieces 6-9 by the effect of the generated Coriolis' force.
