FIRE DOOR
To provide a fire door configured to cause the time flame erupts to be postponed when a control unit is ignited by heating.SOLUTION: A fire door 1 includes: a drive unit 30 that drives a first sliding door 20A and a second sliding door 20B; a control unit 35 that controls the drive unit 30; and a case 40 that houses the drive unit 30 and the control unit 35 and that has a bottom surface opening 40B. The control unit 35 is located farther away from the drive unit 30 when the position of the bottom surface opening 40B is used as a reference.SELECTED DRAWING: Figure 2
【課題】加熱によって制御部が発火したときの火炎が噴出するまでの時間を延ばした防火戸を提供する。【解決手段】防火戸１は、第１引戸２０Ａ及び第２引戸２０Ｂを駆動する駆動部３０と、駆動部３０を制御する制御部３５と、駆動部３０及び制御部３５を収容し下面開口４０Ｂを有するケース４０とを備える。制御部３５は、下面開口４０Ｂの位置を基準としたとき、駆動部３０よりも遠い位置に配置される。【選択図】図２
