PURPOSE:To automatically close the valve of an LP gas when an earthquake occurs, by actuating a hitting bar tripping piece by a vibration and driving a rubber rope wound cylinder by a hitting bar providing a weight. CONSTITUTION:If a device is shaken by an earthquake, a hanging cylinder 2, also being shaken, is dislocated from a flexible thin steel piece 1 pulling a string 8, and the device, lowering the end of a hitting bar tripping piece 9 downward and dropping a hitting bar 3 to the bottom, strongly hits the hitting bar receiving piece of a rubber rope wound cylinder 10 by a hitting part 4 of the hitting bar. The hitting bar 3, providing a hitting bar weight 14, strongly hits the hitting bar receiving piece with the hitting part 4 of the hitting bar. In this way, the device, rotating the rubber rope wound cylinder 10 and loosening a rope 12, closes the valve of an LP gas cylinder 18. |
