ABSTRACT:
The purpose of the invention is to make it possible to adjust the heating rate inside the thermostat independently from the characteristics of the resilient plate in a thermostat, and to reduce the contamination inside the thermostat caused by particles.
A fixing member is fabricated by folding a sheet of metal with at least a couple of holes having different diameters, so that the holes are aligned to each other, and the fixing member is configured so that the larger diameter part of the hole is far from the bimetal, the fixing member is penetrated by protrusions in the fixed plate, and the top of the protrusion is melted to spread in the larger diameter part.
