• a first wall provided on the first partitioning member;
• and
• a second wall provided on the second partitioning member,
• wherein the first and the second partitioning members define the fire-prevention region,
• wherein the plurality of walls forms a labyrinth-shaped gap between the first and the second partitioning members,
• wherein each of the plurality of walls is a spring wall that contains a refractory material and functions as a spring, and includes a front end part,
• wherein, when the first and the second partitioning members are stationary with respect to each other, the front end part is not in contact with a facing member, and
• wherein, when the first and the second partitioning members move closer to each other, the plurality of walls comes into contact with the facing member and is elastically deformed.
