漬しないようになっている。In a molten metal holding furnace that handles molten metal such as aluminum, a molten metal level detection device is used to keep the depth at which the ladle is immersed in the molten metal constant and to pump out a certain amount of molten metal. This hot water level detection device usually consists of a hot water level detection rod and a metal shaft.The hot water level detection rod is electrically connected to the metal shaft, and the metal shaft connects to the molten metal via a ladle. Because they are electrically connected, current flows through the circuit when the level detection rod comes into contact with the molten metal, preventing the ladle from immersing any deeper into the molten metal.

It is very convenient because it can join two parts together, but
When used at high temperatures, the metal spring softens and loses its repulsive force, so it loses its ability to prevent the shaft from coming off and cannot be used as a joining means.

も入り込んでいる。Shape memory alloys are extremely elastic in the martensitic state; once they have memorized a certain shape and are transformed into the martensitic state, even if they are elastically deformed into an arbitrary shape, they will not exceed the transformation temperature. It has the property of returning to its original shape when heated. The locking pin 7 is made of such a shape memory alloy, and when heated above the transformation temperature and restored to its original shape, it expands in the annular space 6 and expands not only in the second annular groove 5 but also in the annular shape. It also penetrates into the groove part 3.

A shape having a radius of curvature larger than the radius of curvature of the first annular groove 3 formed on the inner periphery of the insertion hole of the member 1 is memorized, and a shape having the radius of curvature of the second annular groove 5 is formed at a temperature in the martensitic region. It deforms and fits into the second annular groove 5 of the shaft body 4. The shaft body 4 with the fixing pin 7 fitted therein is inserted into the insertion hole of the member 1. For example, as shown in FIG. 6, the first annular groove 3 of the member 1 has a semicircular +i surface with a radius r, and the shaft body
The second annular groove 5 has a cross section with a diameter D (2r) and a depth d, and the depth d has a length greater than or equal to the diameter D (2r). A groove portion 5 is formed.

As a result, the stopper pin 7 is pushed outward from the second annular groove 5 within the annular space 6 and is located so as to coexist with the first annular groove 3.
このように止めビン７が環状空間部６内に収容されｔ：
後記憶させた形状に復帰すると、両溝状溝部３及び５に
またがって位置しているので、軸体４が部材１に対して
軸線方向に移動するのを完全に阻止することができる。In this way, the stopper bottle 7 is accommodated in the annular space 6.
When the shape is later restored to the memorized shape, the shaft body 4 is located across both grooves 3 and 5, so that movement of the shaft body 4 in the axial direction with respect to the member 1 can be completely prevented.
