Claims

[Claims for Utility Model Registration] (1) A gimbal having a gimbal axis and rotatably supported by a frame around the axis of the gimbal axis, and the gimbal rotating around an axis perpendicular to the gimbal axis. A rate gyroscope for models, comprising: a flywheel that is freely supported and rotationally driven by a motor; and a centering spring that is provided between the frame and the gimbal and biases the gimbal to a neutral position; The centering spring has a pair of parallel elastically deformable parts connected to each other at both ends, the center of one of the elastically deformable parts is fixed to the gimbal axis, and the center of the other elastically deformable part is fixed to the gimbal axis. A rate gyroscope for models that is a flat torsion spring fixed to the frame. (2) The rate gyroscope for models according to claim 1, wherein the centering spring is made of an elastic plate having a slit in the center, and the pair of elastic deformation portions are formed by portions on both sides of the slit. (3) The model according to claim 1, wherein the centering spring is made of an elastic wire bent into a rectangular frame shape, and the pair of elastic deformation parts are formed by two opposing sides of the elastic wire. Rate gyro.
