STRUCTURE OF LOWER FRAME OF WINDOW SHUTTER
To provide structure of a lower frame of a window shutter which prevents flowing of flame from a gap that has occurred between a base end side portion of the lower frame and a body in the case of fire, in a window shutter device.SOLUTION: A lower frame 6 of a window shutter comprises an upper face 60 that extends toward the outdoor side from a body and a base end side portion, and the base end side portion comprises a first base end side edge (a base end side lower edge for attachment 65') and a second base end side edge ( a base end side lower edge 65), and is attached to the body by fixing the first base end side edge to the body by means of a screw 67, and at least a portion of the second base end side edge alienates from and opposes to the body in a state that the lower frame 6 is attached to the body, and a heat expansion fireproof member 68 is provided on a face that opposes to the body of the second base end side edge (the base end side lower edge 65).SELECTED DRAWING: Figure 25
【課題】窓シャッター装置において、火災時に、下枠の基端側部位と躯体との間に生じた隙間から火炎が回ることを防止する。【解決手段】窓シャッターの下枠６は、躯体から屋外側に向かって延びる上面６０と基端側部位を備え、前記基端側部位は、第１基端側辺（取付用基端側下辺６５´）と第２基端側辺（基端側下辺６５）を備えており、第１基端側辺を螺子６７によって躯体に固定することで当該躯体に取り付けられており、下枠６が前記躯体に取り付けられた状態において、第２基端側辺は前記躯体に対して少なくとも一部が離間して対向しており、第２基端側辺（基端側下辺６５）の躯体に対向する面には、熱膨張耐火部材６８が設けてある、【選択図】図２５
