The purpose of the present invention is to provide an earthquake sensing device which can maintain safety, protect machinery and equipment, and prevent additional accidents by sensing shaking or tilting when an earthquake occurs or a building is dangerously shaken or tilted, and then disconnecting a supplying line for gas or oil in order to stop the operation of devices using dangerous fuel such as a range and a boiler, electrical or electronic devices, or industrial machinery and equipment, and is also to provide an earthquake sensing device which can be effectively used by being mounted in electrical or electronic devices in a house or an office and small producing machinery and equipment by having simple composition, no failure, easy manufacturing, and a small size. Provided in the present invention is the earthquake sensing device which provides an effect of being used by being simply mounted in machinery and equipment with dangerous factors such as small machinery and equipment, which has characteristics of rust prevention against moisture and no failure for a long time by forming a sensing ball for sensing danger inside a body unit, which can be conveniently used by ordinary people with an automatic restoration effect by removing dangerous factors, and which has an advantage of raising safety and exporting effects according to the regulations of a quake-prone country by being formed by a tilt angle of 15 degrees specified by the quake-prone country. |
