Abstract: To provide a compact and high performance gyroscope.A gyroscope (10) comprises an outer frame (11); an inner frame (12) positioned inside the outer frame and supported to be movable in one reciprocating direction; a plurality of proof masses (15) positioned inside the inner frame and supported to be movable in the direction orthogonal to the one reciprocating direction; a plurality of outer support suspensions (13) which connect the outer frame and the inner frame; a plurality of inner support suspensions (14) which connect the inner frame and each of the proof masses; actuators (16) for accelerating each of the proof masses; and detectors (17) for detecting displacement of the inner frame against the outer frame. The actuators oscillate the plurality of proof masses in-phase, and wherein Coriolis forces induced on each of the proof masses are summed up in the inner frame.
