７を介して、サーミスタ等の素子１が収められている。3 to 5, the entire outer shell of the element 1 is made of a magnetic material 6, and the element 1, such as a thermistor, is housed therein via an electrically insulating material 7. There is.

第３図に示す感温素子は、略直方体の形状を有し、先端
部をわずか細目のくさび状に形成し、感熱面７は極力広
範囲に平面部が確保されている。The temperature-sensitive element shown in FIG. 3 has a substantially rectangular parallelepiped shape, and its tip is formed into a slightly narrow wedge shape, and the heat-sensitive surface 7 has a flat surface as wide as possible.

、感温素子又は取付部を変形損傷することなく、ボイラ
缶体８との隙間のない取付けが簡単におこなえる。Figures 6 and 7 show the actual installation state, in which a mounting bracket 3 formed in a substantially U-shape is fixed by welding or the like on the outside of the boiler can body 8. By inserting the element into the gap between the boiler can 8 and the mounting bracket 3, the outer shell 6 of the temperature sensing element is applied with a constant force by magnetic force to the boiler can 8.
It adsorbs and secretly 1. Therefore, the temperature sensing element or the mounting part can be easily mounted without any gaps, without applying excessive force and deforming or damaging the temperature sensing element or the mounting part.

この結果、ボイラ缶体８からの熱伝達が、素子１に（ｌ
ｌｉ実に出来、精度の旨い温度検出が可能となる。As a result, heat transfer from the boiler can body 8 to the element 1 (l
This makes it possible to accurately detect temperature.

取付金具３は取付時の位置決め、連送中の衝撃による感
温素子のズレ防止に有効である。The mounting bracket 3 is effective for positioning during installation and for preventing displacement of the temperature sensing element due to impact during continuous feeding.

磁性体材料でも良い。The approximately trapezoidal temperature-sensing element shown in Fig. 5 is effective when the mounting bracket 3 is not used, making the entire structure lightweight and ensuring a large suction surface. Various types of VC can be easily considered, and some of them may be made of magnetic material.

発明の効果 以」ニのように本発明の感温素子によｔ′シは次の効果

（１）素子の外かくの一部又は全体を磁性体材料で構成
しているので、他の取付構造物の力を借りずに、感温素
子自体が磁力によって一定の力て、鉄５製の缶体等に密
着するため、寸法誤差等による取イ」部の隙間も生ぜず
、精度の商い温度検出が出来る。(1) Part or all of the outer shell of the element is made of magnetic material, so the temperature sensing element itself is made of iron 5 with a constant magnetic force without relying on the force of other mounting structures. Since it is in close contact with the can body, etc., there is no gap between the edges due to dimensional errors, etc., and temperature can be detected with high accuracy.

（２）磁力によって一定の力で吸着しており、素子自体
又取付部に対し必要以上の力がかからす、取付時の損傷
の恐れがない。(2) It is attracted with a constant force by magnetic force, so there is no risk of damage during installation due to excessive force being applied to the element itself or the mounting part.
