FIRE-RESISTANT MEMBER

A thermally expandable member housing (17) is formed on an inner surface side of a main body portion (3). An inner diameter of the thermally expandable member housing (17) is slightly larger than thicknesses of other parts of an inner periphery surface of the main body portion (3), and the thermally...

Beschreibung
Zusammenfassung:	A thermally expandable member housing (17) is formed on an inner surface side of a main body portion (3). An inner diameter of the thermally expandable member housing (17) is slightly larger than thicknesses of other parts of an inner periphery surface of the main body portion (3), and the thermally expandable member housing (17) is formed over an entire circumference of the inner surface of the main body portion (3). The thermally expandable member housing (17) accommodates a thermally expandable member (5), which expands due to heat from a fire or the like, and a metal member (2). The metal member (2) is made of aluminum, for example. The metal member (2) is disposed between the main body portion (3) (the thermally expandable member housing (17)) and the thermally expandable member (5). That is, the metal member (2) is disposed on an outer surface side of the thermally expandable member (5). It is unnecessary for the metal member (2) to cover an entire outer surface of the thermally expandable member (5), and the metal member (2) may be disposed on at least a part of an outer periphery side of the thermally expandable member (5).
