Abstract

PURPOSE:To obtain a vibration sensing operation suitably, by locating a magnetic plate which absorbs and holds a free-moving magnet to be displaced to the center of a support lever linked with the free-moving magnet. CONSTITUTION:A free-moving magnet 14 is located at the center of a ring shape fixed magnet 10 fixed to a support, one end of the magnet 14 is choked with a cover plate 20, a support lever 22 is linked with another end of the magnet 14 and a small sized magnet 24 is fitted to the tip of the lever 22. A magnetic substance spherical body 36 is placed on the magnet 24 or the cover plate 20, and one end of the magnet 14 is held in the state contacted with the cover 20 so that the free-moving magnet 14 can be displaced to a prescribed direction through the operation of repulsive magnetic force between the magnets 14 and 10 due to the deviation of the body 36.
