PURPOSE: To ensure thermo-sensing and eliminate poor insulation by inserting a thermal fuse folded in two segments and piled one over another from an insert hole in a metal fixture, and performing installation while a fixing pawl is pushed and bent.
CONSTITUTION: An insert hole 18 is furnished in the neighborhood of a bend of a metal fixture 14 equipped with a holding part 15 and a mounting part 17. A thermal-fuse is folded in two segments, which are overlapped one over the other, and accommodated in a holding part 15 of the metal fixture 14 in such an arrangement that the body 11a of the fuse is situated up and the part with leads facing down. This thermo-fuse 11 is inserted from the insert hole 18 of the metal fixture 14, and is fastened. Accordingly only the side with the thermo-fuse can be put in contact with an object with rising temperature. This allows temp. sensing free from influence of swell at the tip due to two-folding, and pressure contacting and fixation of the thermo-fuse can be done in a position some apart from the body 11a of the thermo-fuse.
