第１スライド扉６の上端に固定したハンガーローラＨＲ１は、ワイヤαを挿通させる部位を備えると共に、ワイヤαには、挿通部位の戸尻側に位置して当接体（金具）が固定されている。第１スライド扉６の戸尻側（開放方向）への移動時には、前記挿通部位がワイヤα上の当接体を押すことで、ワイヤαは戸尻側（開放方向）へ引き出され、巻取装置９２に巻かれていく。ワイヤαの戸先側（閉鎖方向）への移動に伴ってワイヤαに固定した当接体がハンガーローラＨＲ１の挿通部位に当接して、ハンガーローラＨＲ１を戸尻側から戸先側に向かって押すことで、第１スライド扉６が戸先側（閉鎖方向）に移動するようになっている。閉鎖姿勢にある第１スライド扉６を自閉装置ＤＣ３の付勢力に抗して手動で戸尻側（開放方向）にスライド移動させると、ワイヤαが自閉装置ＤＣ３から引き出されながら戸尻側へ移動して、第１スライド扉６、第２スライド扉７が開放姿勢となる。第１スライド扉６、第２スライド扉７は、例えばタイマーによって、開放姿勢を所定時間維持した後に、自閉装置ＤＣ３の閉鎖力によって、ワイヤαが閉鎖方向へ移動することに伴って戸先側へスライド移動して、開口部５を閉鎖する。 A hanger roller HR1 fixed to the upper end of the first slide door 6 has a portion through which the wire α is inserted, and a contacting body (metal fitting) is fixed to the wire α, positioned on the door bottom side of the insertion portion. there is When the first slide door 6 is moved toward the door bottom side (opening direction), the wire α is pulled out toward the door bottom side (opening direction) by the insertion portion pushing the abutting body on the wire α, and is wound up. It is wound around the device 92 . As the wire α moves toward the door tip side (closing direction), the abutting body fixed to the wire α comes into contact with the insertion part of the hanger roller HR1, and the hanger roller HR1 moves from the door trailing edge side toward the door tip side. By pushing, the first slide door 6 is moved toward the door tip (closing direction). When the first slide door 6 in the closed posture is manually slid toward the door tail side (opening direction) against the biasing force of the self-closing device DC3, the wire α is pulled out from the self-closing device DC3 and moved toward the door tail side. , and the first slide door 6 and the second slide door 7 are opened. After the first slide door 6 and the second slide door 7 are kept open for a predetermined time by a timer, for example, the wire α moves in the closing direction due to the closing force of the self-closing device DC3. to close the opening 5.

このように構成された避難連絡坑ドアにおいて、通常時には、閉鎖姿勢にある開き扉によって開口部１が閉鎖され、閉鎖姿勢にある引き戸によって開口部５が閉鎖されている。災害時等に車両用開口部を形成したい場合には、グレモンハンドルＨ１を回動して第１扉体３の閉鎖姿勢のロックを解除し、第１扉体３を避難連絡坑側Ｂに開放して、係止ロッドＲ１を下動して第１扉体３の開放姿勢を維持し、グレモンハンドルＨ２を回動して第２扉体４の閉鎖姿勢のロックを解除し、第２扉体４を避難連絡坑側Ｂに開放して、係止ロッドＲ２を下動して第２扉体４の開放姿勢を維持することで、車両用開口部を形成する。第１扉体３の開放に先立って、引き戸（第１スライド扉６、あるいは、第１スライド扉６及び第２スライド扉７）を開放し、第１扉体３の面部に作用する圧力を軽減してから第１扉体３を開放してもよい。開き扉の開放時において、先に開放させる第１扉体３のグレモンハンドルＨ１が、後に開放させる第２扉体４のグレモンハンドルＨ２よりも手前に位置しており、かつ、正面（内側見付面３００）に設けてあるので、グレモンハンドルＨ１を掴んで行う第１扉体３の開放操作性が良い。 In the thus constructed evacuation tunnel door, the opening 1 is normally closed by the hinged door in the closed position, and the opening 5 is closed by the sliding door in the closed position. When it is desired to form an opening for a vehicle in the event of a disaster, etc., the gremon handle H1 is turned to unlock the first door body 3 in the closed posture, and the first door body 3 is opened to the evacuation tunnel side B. Then, the locking rod R1 is moved downward to maintain the open position of the first door body 3, the Gremont handle H2 is rotated to unlock the second door body 4 in the closed position, and the second door body 4 is opened to the evacuation passage side B, and the locking rod R2 is lowered to maintain the open position of the second door body 4, thereby forming the vehicle opening. Prior to opening the first door 3, the sliding door (the first sliding door 6 or the first sliding door 6 and the second sliding door 7) is opened to reduce the pressure acting on the surface of the first door 3. After that, the first door body 3 may be opened. When opening the hinged door, the Gremont handle H1 of the first door body 3 to be opened first is located in front of the Gremont handle H2 of the second door body 4 to be opened later, and Since it is provided on the surface 300), it is easy to open the first door body 3 by grasping the Gremont handle H1.

災害時等に人道用開口部を形成したい場合には、取手Ｈ３を掴んで第１スライド扉６、第２スライド扉７を開放することで、開き扉の閉鎖姿勢を維持したままで、人道用開口部を形成することができる。本実施形態では、突出部３０Ａを形成することで、内側見付面３００が外側見込面３０３を越えて内側見込面３０２から離間する方向に延びることで見付幅を大きくしているので、第１扉体３に設けた開口部５（人道用開口部）の開口幅寸法を狭めることなく（例えば、戸先側縦枠３０の全体の見付幅寸法を戸尻側へ大きくすると、人道開口部の開口幅寸法を狭めることになる）、内側見付面３００の見付幅を、グレモンハンドルＨ１を設けることが可能な程度に大きくすることができる。また、係止ロッドＲ１、補助ローラＧＲは、避難連絡坑側からの正面視において、突出部３０Ａの背後に位置して隠れることになる。 When it is desired to form an emergency opening in the event of a disaster, the first slide door 6 and the second slide door 7 can be opened by grasping the handle H3, thereby maintaining the closed position of the opening door. An opening can be formed. In this embodiment, by forming the projecting portion 30A, the inner viewing surface 300 extends beyond the outer viewing surface 303 in the direction away from the inner viewing surface 302, thereby increasing the viewing width. 1. Without narrowing the opening width dimension of the opening 5 (passenger opening) provided in the door body 3 (for example, if the overall width dimension of the door tip side vertical frame 30 is increased toward the door bottom side, the pedestrian opening However, the width of the inner viewing surface 300 can be increased to the extent that the Gremont handle H1 can be provided. In addition, the locking rod R1 and the auxiliary roller GR are positioned behind and hidden behind the projecting portion 30A in a front view from the side of the evacuation tunnel.
