The basic shape of the shape memory alloy is like a coil spring as shown in the figure, and in this example, it is set to assume the basic shape at about 50°C. Numerals 39 and 39 are protrusions that stop sliding of the sliding pieces 36 and 36 inward at this position, and the sliding pieces 36 and 36 are connected to the guides 37 and 37.
The sliding pieces 36, 36
This prevents only one side from being pulled together when the two are pulled together by the contraction of the shape memory alloy 38. 40...40 are also protrusions and serve to guide the sliding pieces 36, 36 so that sliding can be carried out quickly in one direction (in the direction of the arrow in the figure).

The shielding plate 2 consists of a metal disk 22 having a diameter slightly smaller than the inner diameter of the container 1, and an annular flap 23 made of heat-resistant rubber attached to the outer peripheral surface of the metal disk.
