PCT No. PCT/JP93/01311 Sec. 371 Date May 16, 1994 Sec. 102(e) Date May 16, 1994 PCT Filed Sep. 14, 1993 PCT Pub. No. WO94/07083 PCT Pub. Date Mar. 31, 1994A cassette type gas cylinder, containing liquefied fuel gas, for giving an alarm when the volume of remaining fuel is reduced to a predetermined level or less in order to provide an advanced notice of replacement of the gas cylinder with a simple structure using burst energy of discharged gas. A valve 12 for opening and closing the discharge of liquefied gas is arranged at the center on one end of a container body 11a. A gas flow channel 17, with one end thereof opened into a gas space formed above the level of the fuel when the gas cylinder is laid horizontally, is connected to the valve 12. A vibrating member 27, for producing a sound when vibrated and caused to collide with a body by the burst of the fuel gas, is disposed in the gas flow channel 17. This vibrating member 27 is connected to a damping member 38 by means of a coupling member 29. The damping member 38 is located below a predetermined level of the liquefied fuel gas, and is subjected to resistance while moving in the liquefied fuel gas. The damping member 38 suppresses the production of a collision sound made by the vibrating member 27 by providing the vibrating member 27 with resistance when the level of the liquefied fuel is above the predetermined level, but does not suppress the production of the collision sound when the level of the liquefied fuel is below the predetermined level, thereby giving an alarm indicating the reduction of remaining fuel.
