Abstract

PURPOSE:To provide a breaker system using a steel ball that falls down in response to a certain magnitude of vibration to shut off a fuel feeding means, in which when replacing the steel ball back onto the pedestal, the ball is first attached to a ring-shaped member above the pedestal and then securely placed in the correct position on the pedestal. CONSTITUTION:When an earthquake has occurred, and if the vibration is in excess of a preset magnitude a steel ball B falls off the pedestal 11 aganist its magnetic attractive force onto a receiving pan below and the resulting shock causes a moving arm 5 to turn arround the pivot 4. When replacing the steel ball B, which has fallen down, back onto the pedestal 11, the arm 5 is turned upward into its initial position and thereafter the steel ball B is pulled up by a string 14 to attach it to the ring-shaped member 15 from below and then slowly lowered into the correct position on the pedestal 11.
