Abstract
An angular velocity sensor device includes a structure having an angular velocity detecting element and a vibration body formed thereon. The structure is mounted on the case and the angular velocity detecting element is isolated from external vibrations without the need for rubber and gel vibration dampening materials. Permanent magnets of the same polarity are mounted opposite one another on the structure and the case. The magnetic repulsion is generated between the structure and the case to cause the structure to be housed within the case in a levitated state.
Claims11
An angular velocity sensor device comprising;
- a case;
- a structure housed within the case and including an angular velocity detecting element with a vibration body mounted thereon;
- means for generating magnetic repulsion between the case and the structure so that the structure is maintained within the case in a levitated state to isolate the structure from external vibrations.
