The pendulum assembly 2 comprises the permanent magnet 3 disposed in the vicinity of the pendulum 2a, the U-shaped yoke 4 by which most of the magnetic flux of the permanent magnet 3 is gathered and passes through, and the rotation shaft 6. The direction of axis of the rotation shaft 6 is parallel to the direction of magnetic poles of the permanent magnet 3. The eddy current brakes 5 are inserted into the spaces between one of the magnetic poles of the permanent magnet 3 and one of the ends of the yoke 4, and between the other magnetic pole the magnet and the other end of the yoke 4. This construction achieves a more compact and shorter tilt sensor which is resistant to disturbances such as geomagnetism and other magnetic fields and vibrations. <IMAGE> |
