PURPOSE:To improve detection sensitivity by supporting a tuning fork which has large inertial mass and a flat plate type flection part and oscillates with large amplitude on a base by a couple of stripped bimorph elements. CONSTITUTION:A thin plate type piezoelectric element 30 which consists of stripped bimorph elements almost at right angles to the top surface of the flat plate type base 2 and detects an input angular velocity OMEGA is fitted onto the base 2. Further, an L-shaped fitting part 1-4 having one leg 1-4b extending toward an oscillation mass part 1-1 is provided to the base 1-3 of the tuning fork 1. The piezoelectric element 30 for detection fitted to the base 2 pierces a center gap (g) by running almost in the center of gravity of the tuning fork 1, etc., and the leg 1-4b of the L-shaped fitting part is coupled with the other terminal. |
