PURPOSE:To enable offset of moire component signals due to an assembly slippage and an inertial force of disturbance against each other by disposing piezoelectric vibrators for detection so that the respective detecting surfaces thereof are symmetric with a plane containing a detection axis and do not intersect this plane perpendicularly. CONSTITUTION:Piezoelectric vibrators 2 for driving and piezoelectric vibrators 1a and 1b for detection constitute a sensor element, being joined respectively by joining members 6 so that they are parallel to a detection axis 7 and intersect each other at right angles, and the free ends on one side of the vibrators 2 are joined to an electrode block 3 by soldering, so as to form a tuning fork structure. The block 3 is supported by a supporting rod 4 and further the other end of the supporting rod 4 is connected to a base 5. The vibrators 1a and 1b and the vibrators 2 joined in the right intersection respectively are disposed so that the respective detecting surfaces of the vibrators 1a and 1b are symmetric with a plane containing the detection axis and do not intersect the plane containing the detection axis perpendicularly. Signals outputted from the vibrators 1a and 1b are detected by discrete detecting circuits and adjusted so that an output at the time when an angular velocity component is zero, and thereby a moire signal, which is a drift component, can be adjusted. |
