成る地震時ガス自動停止装置。[Scope of Claim for Utility Model Registration] A part of an arm provided with a gas outlet for blocking a gas outlet at an appropriate location is engaged with an arm fulcrum, and a spring attachment part provided near the tip of the arm and an extension of the other end are engaged. A spring is installed in an extended state between the provided spring fulcrum, and the position of the spring fulcrum is such that the spring fulcrum is slightly on the packing mounting side, rather than the spring mounting portion, the arm fulcrum, and the spring fulcrum being substantially in a straight line. The arm is configured to be adjustable with an adjustment screw so that it is biased toward the opposite side of the gas outlet, so that the arm rotates with the arm fulcrum as the rotation axis toward the side where the gas outlet is attached by a slight vibration, thereby blocking the gas outlet. This automatic gas shutoff device in the event of an earthquake is equipped with a reset rod with a return spring for returning the arm to its original position by pushing the side of the arm where the gasket is attached from the outside.

成る地震時ガス自動停止装置。 A part of the arm provided with a gas outlet for blocking the gas outlet in a proper place is engaged with the arm fulcrum, and the spring attachment part provided near the tip of the arm and the spring fulcrum provided on the extension of the other end are connected. The spring is installed in an extended state, and the position of the spring fulcrum is adjusted so that the spring fulcrum is slightly biased to the side opposite to the side where the gasket is attached, rather than the spring attachment part, the arm fulcrum, and the spring fulcrum being almost in a straight line. It is configured to be adjustable with a screw, so that with a slight vibration, the arm rotates about the arm fulcrum as the rotation axis to the side where the gas outlet is attached, blocking the gas outlet, and the arm gasket is attached from the outside. This automatic gas shutoff device is equipped with a reset rod with a return spring to return the arm to its original position by pushing the opposite side.
