    摘要： A tuning-fork vibration gyro includes a tuning-fork vibrator having two arms and a base portion, and a supporting portion located in a center of a rotational motion of the base portion caused by a vibration resulting from a Coriolis force. The supporting portion protrudes from two surfaces of the base portion opposite each other in a direction in which the vibration resulting from the Coriolis force occurs.

    摘要： A tuning fork type vibrator including two arms and a base is supported by a supporting substrate mounted on a stem, and an oscillation limiting member formed from a ring-shaped rubber-like elastic body is mounted with its one face secured to the stem so as to surround the base. When an external vibration or impact is applied, the tuning fork type vibrator oscillates in response to the vibration or impact, but the oscillation range of the tuning fork type vibrator is limited by the presence of this oscillation limiting member, and thus bumping of the tuning fork type vibrator against the surrounding members such as the stem is prevented. Moreover, a gyro characteristic is not impaired, and a loss of the gyro function due to a stop of drive vibration does not occur.

    摘要： The shape of drive electrodes and/or the shape of detection electrodes of a tuning fork type vibration gyro are made asymmetrical between the inside and outside of the arm, and between the surface and reverse face of the arm, to reduce the abnormal vibration and leaking output. The drive electrodes to be provided on the inside parts of the surface and reverse face of the first arm are formed smaller than the drive electrodes to be provided on the outside parts of the surface and reverse face thereof. The length of the detection electrode to be provided on the outside lateral face of the second arm is formed short. The drive electrodes to be provided on the surface and reverse face of the first arm are extended to the base side from the boundary position between the first arm and the base, and the detection electrodes to be provided on the surface and reverse face of the second arm are extended to the base side from the boundary position between the second arm and the base.

    摘要： In a tuning fork type vibration element provided in a tuning fork type vibration gyro, the sum of inertial moments of a base to an inertial moment of two arms is 1.0 or larger. The inertial moment of the two arms is obtained by multiplying the square of a rotation radius, which is a distance from a center axis of torsional vibration as a center position between the two arms to a center of gravity of the two arms with a mass of the two arms, and the inertial moment of the base is obtained by multiplying the square of the rotation radius from the center axis of the same torsional vibration.
