PURPOSE:To enhance workability by a simple structure and to eliminate operative inferiority caused by boiling-out, by supporting a heat-sensitive part, wherein a disc shaped head equipped with a temp. detection element is fixed to a cylindrical case, in an up-and-down movable manner by the upper end of a guide. CONSTITUTION:A disc shaped head 11 equipped with a temp. detection element 19 is fixed to a cylindrical case 12 to constitute a heat-sensitive part 10 while a guide 15 is constituted of expanded parts 16 and projection parts 17 downwardly extending from said expanded parts 16 toward both sides and the heat-sensitive part 10 is supported in an up-and-down movable manner through a spring 23 so as to to provide the intervals 22 between the expanded parts 16 and the heat-sensitive part 10. Further, the hooking part 14 provided to the lower end of the case 12 is inlaid with the projection parts 17 to attach the heat-sensitive part 10 and the guide 15 while the gap between the hooking part 14 and the guide 15, the gaps between the case 12 and the projection parts 17 and intervals 22 are made almost same to connect the element 19 to a lead wire 21 through a transit part 20. By this mechanism, the hooking part 14 is prevented not only from pulling-out by the expanded parts 16 hooked with said hooking part 14 but also from turning by the projection parts 17 hooked therewith and the heat-sensitive part 10 can be certainly held. |
