また、第２の乗場ドア４の上部は、ドアレール２により回転支持されているが、第２のドアハンガ９が対向端部２１ａに押し当てられた状態では、図５に示すように、傾斜規制部材２１により固定支持される構造となる。このため、第２のドアパネル８が乗場側から負荷を受けた際の撓み角が小さくなり、第２の乗場ドア４の変形を小さくすることができる。
Further, the upper part of the second landing door 4 is rotatably supported by the door rail 2, but in a state where the second door hanger 9 is pressed against the opposing end 21a, as shown in FIG. The structure is fixedly supported by 21. For this reason, the bending angle when the second door panel 8 receives a load from the landing side is reduced, and the deformation of the second landing door 4 can be reduced.
これにより、第２の乗場ドア４の剛性を弱くすることが可能であり、補強を省略したり板厚を小さくしたりすることができる。例えば、第２のドアパネル８は、その両端部を除いて平滑な平面のみの構成とすることもできる。
Thereby, it is possible to weaken the rigidity of the second landing door 4, and the reinforcement can be omitted or the plate thickness can be reduced. For example, the 2nd door panel 8 can also be set as the structure of only a smooth plane except the both ends.
さらに、第１及び第２の乗場ドア３，４の全閉時には、引っ掛け部１２ａが第１のドアハンガ６の昇降路側にラップしているため、第１のドアハンガ６の傾斜も規制され、第１のドアハンガ６のドアレール２からの脱落も防止することができる。
Further, when the first and second landing doors 3 and 4 are fully closed, the hooking portion 12a wraps on the hoistway side of the first door hanger 6, so that the inclination of the first door hanger 6 is also restricted. The door hanger 6 can be prevented from falling off the door rail 2.
さらにまた、傾斜規制部材２１が取付板１１に一体に設けられているため、部品点数の増加を防止することができる。
