PROBLEM TO BE SOLVED: To prevent the reduction of productivity and safety even in a radiator and a receiver tank of a refrigerator using different kinds of refrigerants. SOLUTION: This fusible plug 27 is composed of a case 44 provided with two plug holes 43 or more, metallic plugs 45 formed by materials having different melting points and mounted in the plug holes 43, respectively, and a plug lid 46 putting a lid on the plug hole 43 in which other metallic plug 45 is mounted to let the metallic plugs 45 having melting point suitable for refrigerant used in the refrigerator function. Consequently, productivity and safety are not reduced even in the refrigerator using different kinds of refrigerants. COPYRIGHT: (C)2005,JPO&NCIPI
