<p>PROBLEM TO BE SOLVED: To obtain an electromagnetic apparatus (gas discharge lamp) wherein a thermosensitive element can be easily fixed in close contact with a laminated core, close contact property can be maintained for a long term, and thermosensitive precision and protective performance of the thermosensitive element can be improved. SOLUTION: A stabilizing main body (electromagnetic apparatus main body) 21 provided with a first coil 22 and a second coil 23 which are arranged parallel with each other, and a laminated core 23 which is combined with the coils is caulked by a case 35 and a bottom plate 34 which are arranged so as to cover the periphery of the stabilizer main body. A gas discharge lamp stabilizer (electromagnetic apparatus) is provided with a thermosensitive element 33 for detecting the temperature of the coils 22, 23. The thermosensitive element 33 is arranged between flanges 25a and 27a of bobbins 25, 27 of both coils protruded from one side core surface 24a of the core 24. A clamping protrusion 30 for clamping the element 33 to the core surface 24a is formed in at least one of the flanges 25a, 27a. Thereby the element 33 inserted in the part between both of the bobbins 25 and 27a is closely brought into contact with the core surface 24a and held by using the clamping protrusion 30.</p> |
