SLIDING DOOR AND FITTING
PROBLEM TO BE SOLVED: To prevent flaming from a door roller portion.SOLUTION: A bottom rail 34 has a bottom rail hollow portion 341 extending along the longitudinal direction of the bottom rail 34. A communication hole, which establishes a fluid communication between the bottom rail hollow portion 341 and its outside, is formed in a lower wall portion 346 of the bottom rail hollow portion 341. A door roller portion 7, which is provided inside the bottom rail hollow portion 341, extends partly to the downward through the communication hole. Inside the bottom rail hollow portion 341, there is provided a non-flammable or flame retardant bottom rail reinforcing member 8 that extends along the longitudinal direction of the bottom rail 34 to reinforce the bottom rail 34. The bottom rail reinforcing member 8 is provided with a non-flammable or flame retardant door roller facing portion 9 facing the door roller portion 7.SELECTED DRAWING: Figure 2
【課題】戸車部からの発炎を防止すること。【解決手段】下框３４は、当該下框３４の長手方向に沿って延在する下框中空部３４１を備える。下框中空部３４１における下方の壁部３４６には、当該下框中空部３４１と外部とを連通する連通孔が形成されている。戸車部７は、下框中空部３４１の内部に設けられ、一部が連通孔を介して下方に突出する。下框中空部３４１の内部には、下框３４の長手方向に沿って延在し、下框３４を補強する不燃性または難燃性の下框補強材８が設けられている。下框補強材８には、戸車部７に対向する不燃性または難燃性の戸車対向部９が設けられている。【選択図】図２
