用突子である。In FIG. 1, reference numeral 1 is a hollow insert body (for example, made of resin), one end 11 is formed in a pointed shape, and a stopper (flange) 12 is formed at the other end. Reference numeral 13 is a locking claw. 2 is a detection rod (for example, made of resin) with a round head at the tip
21. The round head 21 is lightly locked to the locking projection 14 at the distal end (one end) of the hollow insert body. 22 is a stopper provided in the middle of the detection rod 2. 3 is a coil-shaped shape memory alloy inserted into the tip of the detection rod (for example,
The Ni-Ti type detection rod 2 is supported by its stopper 22. Reference numeral 15 is a locking protrusion formed at the other end of the hollow insert.
上記コイル状形状記憶合金３の記憶形状は第２図に示す
通りの伸長状態である。The memorized shape of the coil-shaped shape memory alloy 3 is in an expanded state as shown in FIG.
上記において、コイル状形状記憶合金が変態温度に達し

峻に大きく突出する。In the above, even when the coil-shaped shape memory alloy reaches the transformation temperature and tries to expand, the detection rod 2 initially moves because the tip head 21 of the detection rod 2 is locked by the locking projection 14. The expansion of the coil-shaped shape memory alloy 3 is suppressed by the stopper 22 and the coil-shaped shape memory alloy 3 is compressed. This compressive force is the locking protrusion of the tip head 21 of the detection rod 2.
When the fixing force (locking force) by 14 is exceeded, the detection rod 2 is unfixed, and the coil-shaped shape memory alloy 3 that was held by the stopper 22 until then stretches all at once due to its spring elasticity. The detection rod 2 sharply and largely projects from the inside of the hollow insert body 1.

得る。Therefore, the coil-shaped shape memory alloy that expands at the transformation temperature and returns to the memorized shape, whose transformation temperature is a predetermined temperature is used, and the object to be heated is visually detected by the sharp large protrusion of the detection rod. One can certainly know when is above a certain temperature.
被加熱材料が冷めたのち、検出棒を指で押えてその先端
丸頭をインサート体内突子に係止しておけば、当該温度
センサの再使用が可能である。After the material to be heated has cooled, the temperature sensor can be reused by pressing the detection rod with a finger and locking the rounded tip of the detection rod to the insert body protrusion.
