Abstract

PURPOSE: To provide a vibration sensor which exhibits stable sensing action on an average for vibration frequencies over a wide and unspecified range such as those of earthquake by disposing two weights each having a varying resonance frequency from the other under different vibration conditions and combined with each other via a magnet.
