Abstract

PURPOSE: To provide a device suitable for use in bearing axle boxes and capable of generating warning under high temperature by a structure that can discharge a closure plug means from the device by the force exerted from a heat detecting means, and generate a signal when the plug means is discharged. CONSTITUTION: When the temperature around a device 10 rises to a temperature at which the alloy 20 is melted, a spring 18 pushes upward a driver 26 in the direction of a closure plug 50 and discharge the plug 50 out of the device 10 by the small section of a pin 30. When the closure plug is struck as if by a hammer, the gap between the plug and the distal end of the pin 30 produces kinetic energy so that even if the closure plug 50 is contaminated seriously, it is struck by the interior mechanism which is not contaminated and pushed out forcibly. When the closure plug 50 is discharged, the pin 30 extends beyond a head 14 to expose a reversed reflecting disc 42 so that it is possible to produce a temperature warning having a broad surface easy to be seen.
