Abstract
The specification discloses an angular velocity and acceleration sensor in which a tuning-fork oscillator is vibrated on the main driven vibrating axis and displacement on an axis which is parallel to the main driven vibrating axis or displacement which crosses it at right angles is detected so that at least one of angular velocity and acceleration on an axis which is parallel to the main driven vibrating axis or which crosses it at right angles may be detected. The sensor is characterized in that vibrating reeds of the tuning-fork oscillator are so formed that the spring constant of the vibrating reeds on the main driven vibrating axis is substantially equal to that on the axis which crosses the main driven vibrating axis at right angles.
