Fire extinguisher having a heat fusible member under compression
 The present invention relates to a fire extinguisher which comprises vessels (1, 18)filled with a fire extinguishing solution, an actuating element that breaks the vessels to eject the solution due to the occurance of fire. The actuating element is retracted against the force of a spring by a holder which is locked by a set screw (41) for exerting a pressure thereto through a heat fusible element (42) for fire detection so that the heat fusible element (42) is placed perpetually under compression. Since the heat fusible element (42) is normally subjected to compression, the element is less liable to deterioration with time.
