しかしながら、特許文献１に記載されたエレベーター装置は、乗りかごの気密性を保つ弾性体からなる気密部材をかごドアの戸閉力によって弾性変形させているため、かごドアの戸閉力を増強する必要があり、それが不十分の場合には戸当り部に隙間が形成されてしまう。   However, since the elevator apparatus described in Patent Document 1 elastically deforms the airtight member made of an elastic body that keeps the airtightness of the car by the door closing force of the car door, the door closing force of the car door is increased. If necessary and insufficient, a gap is formed in the door stop.

上記課題を解決するために、本発明のエレベーター装置は、側面を形成する側板と、乗降口と、前記乗降口の前面で開閉するかご戸とを有する乗りかごを備えるエレベーター装置において、前記かご戸が戸開状態の場合に前記かご戸と対向する前記側板に上下方向に延びて設けられ、水平断面において前記かご戸側に延びて設けられる曲げ変形可能な第一の部材と、前記かご戸の面上で上下方向に延び、水平断面において前記側板側に延びて設けられる曲げ変形可能な第二の部材と、前記かご戸が戸開状態の場合に前記かご戸と対向する前記側板において、前記第一の部材よりも前記乗降口側に設けられ、前記乗降口へ近づく方向への前記第一の部材の変形を規制する乗りかご側規制部と、前記かご戸において、前記第二の部材よりも前記乗降口から離れる側に設けられ、前記乗降口から離れる方向への前記第二の部材の変形を規制するかご戸側規制部とを更に備え、前記かご戸が戸閉状態の場合に、前記第一の部材の少なくとも一部と前記第二の部材の少なくとも一部とが接触することで、前記第一の部材と前記第二の部材との間の隙間が塞がれる構成とした。   In order to solve the above-described problems, an elevator apparatus according to the present invention is an elevator apparatus including a passenger car having a side plate that forms a side surface, a passenger door, and a car door that opens and closes in front of the passenger door.

以下、本発明の実施例を図面に基づいて説明する。   Embodiments of the present invention will be described below with reference to the drawings.

図１は、本発明を適用するエレベーター装置に備えられる乗りかごの外観斜視図である。   FIG. 1 is an external perspective view of a car provided in an elevator apparatus to which the present invention is applied.

乗りかご１は、側面を形成する側板５ａと、乗客が乗り降りするための乗降口１ａと、乗降口１ａの前面で開閉するかご戸２を備えている。また、乗りかご１の上部には気圧制御装置としての吸気フロア３および排気フロア４が設けられている。気圧制御装置は、乗りかご１が昇降路内を昇降するときに内部圧力が変動するのを抑制するために吸気ブロア３および排気ブロア４などを制御して、乗りかご１内の圧力を昇降路内の気圧と近似するように制御するものである。   The car 1 includes a side plate 5a that forms a side surface, an entrance 1a for passengers to get on and off, and a car door 2 that opens and closes in front of the entrance 1a. In addition, an intake floor 3 and an exhaust floor 4 as an atmospheric pressure control device are provided on the upper portion of the car 1. The atmospheric pressure control device controls the intake blower 3 and the exhaust blower 4 in order to suppress the internal pressure from fluctuating when the car 1 moves up and down in the hoistway, and the pressure in the car 1 is raised and lowered. It is controlled so as to approximate the atmospheric pressure inside.

上述したように乗りかご１には開閉可能なかご戸２が設けられているおり、かご戸２が閉じられた状態でもその近傍から乗りかご１の内外が簡単に連通してしまうと、連通箇所で気圧の変化が生じ、気圧制御装置以外の要因によって気圧が変化してしまうため、気圧制御装置による気圧制御効率を低下させてしまう原因となる。この気圧制御効率の低下を緩和するため、乗りかご１の近傍には気密構造を構成されており、次に、本発明の気密構造について説明する。   As described above, the car 1 is provided with the car door 2 that can be opened and closed. Even when the car door 2 is closed, if the inside and outside of the car 1 can easily communicate with each other, Since the atmospheric pressure changes due to factors other than the atmospheric pressure control device, the atmospheric pressure changes due to factors other than the atmospheric pressure control device, which reduces the atmospheric pressure control efficiency of the atmospheric pressure control device. In order to mitigate this decrease in atmospheric pressure control efficiency, an airtight structure is formed in the vicinity of the car 1, and the airtight structure of the present invention will be described next.

図２は、かご戸２の近傍を示す水平断面図である。   FIG. 2 is a horizontal sectional view showing the vicinity of the car door 2.

乗りかご１の乗降口１ａが形成されるかご室５には、乗降口１ａと隣接する側板５ａの乗降口１ａ側端部が、乗りかご１の外側であるかご戸２側へほぼ直角に折り返されることで乗りかご側規制部６が形成されている。側板５ａよりも乗りかご１の外側に配置されたかご戸２は、乗りかご側規制部６との間に第一の間隙７を有し、乗降口１ａが形成される側面に平行して開閉動作可能に構成されている。図２は、かご戸２が全開時の状態を示しており、このときかご戸２の乗降口１ａ側端部は、乗りかご側規制部６付近に位置している。   In the car room 5 in which the passenger door 1a of the passenger car 1 is formed, the end of the side plate 5a adjacent to the passenger door 1a is folded at a substantially right angle toward the car door 2 side outside the passenger car 1. As a result, the car-side regulating portion 6 is formed. The car door 2 disposed on the outer side of the car 1 with respect to the side plate 5a has a first gap 7 between the car side restricting portion 6 and opens and closes in parallel with the side surface on which the passenger door 1a is formed. It is configured to be operable. FIG. 2 shows a state in which the car door 2 is fully opened. At this time, the end of the car door 2 on the entrance / exit 1a side is located in the vicinity of the car-side regulating portion 6.

一方、かご戸２の乗降口から離れる側（戸袋側）の端部には、第一のブラケット８が溶接によって結合されている。この第一のブラケット８を利用して、第二のブラケット９がボルト１０によって固定されている。なお、かご戸２と第一のブラケット８との間の結合および、第一のブラケット８と第二のブラケット９との結合は、溶接による固定であっても、ボルトによる固定であっても良い。また、第一のブラケット８と第二のブラケット９とが一体の部材で構成されていても良い。   On the other hand, the first bracket 8 is joined to the end of the car door 2 on the side away from the entrance / exit (door side) by welding. The second bracket 9 is fixed with bolts 10 using the first bracket 8. The connection between the car door 2 and the first bracket 8 and the connection between the first bracket 8 and the second bracket 9 may be fixed by welding or fixed by bolts. . Moreover, the 1st bracket 8 and the 2nd bracket 9 may be comprised with the integral member.

図３は、図２における乗りかご側規制部６近傍の拡大図である。   FIG. 3 is an enlarged view of the vicinity of the car side regulating portion 6 in FIG.

開状態のかご戸２と対向した位置の側板５ａには、閉状態のかご戸２および第二のブラケット９と衝突することのない位置にボルト１１が設けられている。このボルト１１は、   Bolts 11 are provided on the side plate 5a at a position facing the car door 2 in the open state at a position where it does not collide with the car door 2 and the second bracket 9 in the closed state. This bolt 11

乗りかご側規制部６の乗降口１ａから見た裏面側に配置される押さえ具１２と、この押さえ具１２と乗りかご側規制部６間に挟み込んだ０．５ｍｍ程度の厚さを有する薄板状の第一のゴム板１３とを側板５ａに固定している。第一のゴム板１３の自由端は、乗りかご側規制部６の裏面に沿ってかご戸２側に延び、つまり、かご戸２の開閉方向に対してほぼ直交する方向に延びているが、かご戸２との間には第二の間隙１４が形成されている。 A pressing member 12 disposed on the back side as viewed from the entrance / exit 1a of the car-side restricting portion 6 and a thin plate having a thickness of about 0.5 mm sandwiched between the pressing tool 12 and the car-side restricting portion 6 The first rubber plate 13 is fixed to the side plate 5a. The free end of the first rubber plate 13 extends to the car door 2 side along the back surface of the car side restricting portion 6, that is, extends in a direction substantially orthogonal to the opening / closing direction of the car door 2, A second gap 14 is formed between the car door 2 and the car door 2.

第一のゴム板１３は、その自由端から側板５ａの方に少し後退した位置でボルト１１によって固定されているため、その自由端は乗りかご側規制部６から離れる方向（乗降口１ａから離れる方向）に弾性変形可能となっている。しかし、かご戸２との間に第二の間隙１４が形成されているため、かご戸２の開閉動作時にかご戸２と第一のゴム板１３とが接触することはない。従って、かご戸２の開閉動作そのものによって第一のゴム板１３が乗りかご側規制部６から離れる方向に変形させられることはない。   Since the first rubber plate 13 is fixed by the bolt 11 at a position slightly retracted from the free end toward the side plate 5a, the free end is away from the car-side restricting portion 6 (away from the entrance / exit 1a). Direction). However, since the second gap 14 is formed between the car door 2 and the car door 2, the car door 2 and the first rubber plate 13 do not come into contact with each other. Accordingly, the first rubber plate 13 is not deformed in the direction away from the car-side regulating portion 6 by the opening / closing operation itself of the car door 2.

図４は、図２におけるかご戸２の戸袋側近傍の拡大図である。   FIG. 4 is an enlarged view of the vicinity of the door pocket side of the car door 2 in FIG. 2.

かご戸２の戸袋側端面には、０．５ｍｍ程度の厚さを有する薄板状の第二のゴム板１５を挟み込んで保持具１６が配置され、ボルト１７によって第二のゴム板１５および保持板１６がかご戸２に固定されている。この第二のゴム板１５の自由端側は、かご戸２の開閉方向に対してほぼ直交する側板５ａの方向に延びている。   A retainer 16 is disposed on the end surface of the car door 2 with a thin rubber plate 15 having a thickness of about 0.5 mm interposed therebetween, and the second rubber plate 15 and the holding plate are disposed by bolts 17. 16 is fixed to the car door 2. The free end side of the second rubber plate 15 extends in the direction of the side plate 5 a substantially orthogonal to the opening / closing direction of the car door 2.

第二のゴム板１５は、その自由端側から少し後退した位置でボルト１７によってかご戸２に固定されており、その自由端側は図３に示した第一のゴム板１３と同方向に弾性変形可能となっている。しかし、第二のゴム板１５の自由端までの長さは、図３に示した第一のゴム板１３とは接触するが、図３に示したボルト１１や押さえ具１２と接触しないようにされている。従って、かご戸２の開閉動作時に側板５ａと第二のゴム板１５とが接触することはない。   The second rubber plate 15 is fixed to the car door 2 by a bolt 17 at a position slightly retracted from the free end side, and the free end side is in the same direction as the first rubber plate 13 shown in FIG. Elastic deformation is possible. However, the length to the free end of the second rubber plate 15 is in contact with the first rubber plate 13 shown in FIG. 3, but is not in contact with the bolt 11 and the pressing tool 12 shown in FIG. Has been. Therefore, the side plate 5a and the second rubber plate 15 do not come into contact with each other when the car door 2 is opened and closed.

また第一のブラケット８に結合された第二のブラケット９は、かご戸２よりもかご室側に位置し、かつ、第二のゴム板１５の自由端側における乗降口から離れる側で第二のゴム板１５と対向し、かご室側へ延びるかご戸側規制部１８を有している。かご戸側規制部１８は、定常状態では第二のゴム板１５の自由端側における乗降口側から見た裏面に間隙１９を保持している。このかご戸側規制部１８も側板５ａの方に延びているが、第二のゴム板１５と同程度であり、かご戸２の開閉動作時に側板５ａとかご戸側規制部１８とが接触することはない。   The second bracket 9 coupled to the first bracket 8 is located on the cab side with respect to the car door 2 and on the side away from the entrance on the free end side of the second rubber plate 15. A car door side restricting portion 18 that faces the rubber plate 15 and extends toward the car room side is provided. The car door side restricting portion 18 holds a gap 19 on the back surface viewed from the entrance / exit side on the free end side of the second rubber plate 15 in a steady state. The car door side restricting portion 18 also extends toward the side plate 5a, but is about the same as the second rubber plate 15, and the side plate 5a and the car door side restricting portion 18 come into contact with each other when the car door 2 is opened and closed. There is nothing.

図５は、かご戸２の閉状態を示す要部拡大図である。   FIG. 5 is an essential part enlarged view showing a closed state of the car door 2.

乗りかごには、かご戸２が開閉可能に配置されるため、乗りかご側規制部６とかご戸２間には第二の間隙１４がどうしても存在してしまう。しかし、かご戸２の閉状態で、乗りかご側規制部６に取り付けられた第一のゴム板１３と、かご戸２に取り付けられた第二のゴム板１５とは、互いに自由端側が重ね合わさるように互い違いに配置されている。このため、かご戸２の閉状態で、乗りかご側規制部６に取り付けられた第一のゴム板１３の自由端側と、かご戸２に取り付けられた第二のゴム板１５の自由端側とが接触し、第一のゴム板１３と第二のゴム板１５との隙間が塞がれることで、第二の間隙１４が塞がれた状態となる。   Since the car door 2 is disposed in the car such that the car door 2 can be opened and closed, the second gap 14 inevitably exists between the car-side regulating portion 6 and the car door 2. However, in the closed state of the car door 2, the first rubber plate 13 attached to the car-side regulating unit 6 and the second rubber plate 15 attached to the car door 2 are overlapped on the free end side. Are arranged alternately. For this reason, in the closed state of the car door 2, the free end side of the first rubber plate 13 attached to the car side regulating portion 6 and the free end side of the second rubber plate 15 attached to the car door 2. And the gap between the first rubber plate 13 and the second rubber plate 15 is closed, so that the second gap 14 is closed.

しかも、かご戸２の閉状態で、第一のゴム板１３と第二のゴム板１５の重なった部分の乗降口から見た裏側、つまり、かご戸２の開方向には間隙１９が存在するようにかご戸側規制部１８が位置している。間隙１９は、第一のゴム板１３と第二のゴム板１５の重なった部分の弾性変形によって多少変化するが、乗りかご側規制部６とかご戸側規制部１８とによって第一のゴム板１３と第二の１５を圧接することはない。つまり、乗りかご側規制部６とかご戸側規制部１８との間には、第一のゴム板１３と第二のゴム板１５の後述するような弾性変形を許す間隙１９が形成されている。   In addition, when the car door 2 is closed, a gap 19 exists on the back side of the overlapped portion of the first rubber plate 13 and the second rubber plate 15, that is, in the opening direction of the car door 2. Thus, the car door side restricting portion 18 is located. The gap 19 slightly changes due to the elastic deformation of the overlapping portion of the first rubber plate 13 and the second rubber plate 15, but the first rubber plate is formed by the car side regulating portion 6 and the car door side regulating portion 18. 13 and the second 15 are not pressed. That is, a gap 19 that allows elastic deformation of the first rubber plate 13 and the second rubber plate 15 as will be described later is formed between the car-side regulating unit 6 and the car door-side regulating unit 18. .

この状態で気圧制御装置によって乗りかご１内の気圧制御が行われた場合、上述した気密構造は次のように作用する。   When the atmospheric pressure control in the car 1 is performed by the atmospheric pressure control device in this state, the above-described airtight structure operates as follows.

つまり、乗りかご１内の気圧が上昇すると、乗りかご側規制部６とかご戸２間に存在する第二の隙間１４から受圧力が第一のゴム板１３および第二のゴム板１５に作用し、第一のゴム板１３および第二のゴム板１５とが接触状態を保ったままかご戸側規制部１８方向へ弾性変形する。この弾性変形は、第一のゴム板１３および第二のゴム板１５がかご戸側規制部１８の対向面に接触してかご戸側規制部１８への変形（乗降口から離れる方向への変形）が規制される。このとき、第一のゴム板１３および第二のゴム板１５とはかご戸側規制部１８と乗りかご側規制部６との対向部に存在する間隙内でだけ変形移動できるように規制されており、また互いに自由端側が重ね合わさるように互い違いに配置されているため、第一のゴム板１３および第二のゴム板１５が弁のように作用して気密を保持する。   That is, when the atmospheric pressure in the car 1 rises, the received pressure acts on the first rubber plate 13 and the second rubber plate 15 from the second gap 14 existing between the car-side regulating portion 6 and the car door 2. Then, the first rubber plate 13 and the second rubber plate 15 are elastically deformed in the direction of the car door side restricting portion 18 while maintaining the contact state. This elastic deformation is caused by deformation of the first rubber plate 13 and the second rubber plate 15 into contact with the facing surface of the car door side restricting portion 18 to the car door restricting portion 18 (deformation in a direction away from the entrance / exit). ) Is regulated. At this time, the first rubber plate 13 and the second rubber plate 15 are restricted so that they can be deformed and moved only within a gap existing at the facing portion between the car door side restricting portion 18 and the car side restricting portion 6. In addition, the first rubber plate 13 and the second rubber plate 15 act like a valve to maintain airtightness because the free end sides are alternately arranged so as to overlap each other.

一方、乗りかご１内が減圧されると、乗りかご側規制部６とかご戸２間に存在する第二の隙間１４において第一のゴム板１３および第二のゴム板１５に受圧力が作用し、第一のゴム板１３および第二のゴム板１５とは接触状態を保ったまま今度は乗りかご側規制部６側（乗降口側）に弾性変形する。この弾性変形は、第一のゴム板１３および第二のゴム板１５が図示のように乗りかご側規制部６の対向面側に接触して乗降口側への変形が規制される。この場合も、第一のゴム板１３および第二のゴム板１５とはかご戸側規制部１８と乗りかご側規制部６との対向部に存在する間隙でだけ変形移動できるように規制されており、また互いに自由端側が重ね合わさるように互い違いに配置されているため、第一のゴム板１３および第二のゴム板１５が弁のように作用して気密を保持する。   On the other hand, when the inside of the car 1 is depressurized, pressure is applied to the first rubber plate 13 and the second rubber plate 15 in the second gap 14 existing between the car-side regulating portion 6 and the car door 2. Then, while maintaining the contact state with the first rubber plate 13 and the second rubber plate 15, this time elastically deforms to the car side regulating portion 6 side (the entrance / exit side). As for this elastic deformation, the first rubber plate 13 and the second rubber plate 15 come into contact with the opposite surface side of the car-side restricting portion 6 as shown in the figure, and the deformation toward the entrance / exit is restricted. In this case as well, the first rubber plate 13 and the second rubber plate 15 are restricted so that they can be deformed and moved only in the gap that exists between the car door side restricting portion 18 and the car side restricting portion 6. In addition, the first rubber plate 13 and the second rubber plate 15 act like a valve to maintain airtightness because the free end sides are alternately arranged so as to overlap each other.

類似した気密構造として、かご戸側規制部１８と乗りかご側規制部６との対向部にＯリングなどを配置することも考えられるが、このようなＯリングはかご戸２の戸閉力に依存する接触式の密封構造となるため、かご戸２の戸閉力が足らず、戸当り部に隙間が形成されてしまう危険がある。しかしながら、本実施例における気密構造は、乗りかご１内外の気圧差を利用して乗りかごを気密するため、かご戸２の戸閉力を増強する必要がなく、また、図示しないドアマシンの戸閉力をすべて戸当りに使うことできるようになり、戸当りの隙間が形成されることを減少させることができる。   As a similar airtight structure, it may be possible to arrange an O-ring or the like on the opposite part of the car door side restricting portion 18 and the car side restricting portion 6. Since it depends on the contact-type sealing structure, the door closing force of the car door 2 is insufficient, and there is a risk that a gap is formed in the door stop portion. However, since the airtight structure in this embodiment uses the pressure difference between the inside and outside of the car 1 to seal the car, there is no need to increase the door closing force of the car door 2 and the door of the door machine (not shown). All the closing force can be used for the door stop, so that the formation of a gap between door stops can be reduced.

上記の実施例において、かご戸２が戸閉状態の場合に第一のゴム板と第二のゴム板が重なり合わさるが、かご戸２が戸閉状態の場合に常に第一のゴム板と第二のゴム板が重なり合わさるのではなく、乗りかご１の内側の気圧と乗りかご１の外側の気圧との気圧差が所定値よりも小さい場合は重なり合わず、乗りかご１の内側の気圧と乗りかご１の外側の気圧との気圧差が所定値よりも大きい場合に、気圧差による力を第一のゴム板と第二のゴム板とが受けて重なり合わさる構成としてもよい。この場合、少なくとも１hPa以上の気圧差が乗りかご１の内側と外側の間に生じている場合に第一のゴム板と第二のゴム板とが重なり合うことが望ましい。   In the above embodiment, the first rubber plate and the second rubber plate overlap each other when the car door 2 is in the door-closed state, but the first rubber plate and the second rubber plate are always overlapped when the car door 2 is in the door-closed state. The two rubber plates do not overlap, but do not overlap when the pressure difference between the air pressure inside the car 1 and the air pressure outside the car 1 is smaller than a predetermined value, the air pressure inside the car 1 When the pressure difference with the atmospheric pressure outside the car 1 is larger than a predetermined value, the first rubber plate and the second rubber plate may receive and overlap each other due to the pressure difference. In this case, it is desirable that the first rubber plate and the second rubber plate overlap each other when a pressure difference of at least 1 hPa or more is generated between the inside and the outside of the car 1.

また、上記の実施例において、第一のゴム板１３および第二のゴム板１５は０．５ｍｍ程度の厚さとしているが、これに限定するものではなく他の曲げ変形可能な部材を使用することもできる。いずれの場合も、かご戸２と、かご戸２に対して相対的に設けられた乗りかご側規制部６との間に、かご戸２の閉状態で第二の間隙１４を形成し、かご戸２の閉状態で互いに自由端側を重ね合わせて第二の間隙１４を塞ぐようにかご戸２と乗りかご側規制部６とにそれぞれ第一のゴム板１３と第二のゴム板１５のような曲げ変形可能な部材を互い違いに取り付け、曲げ変形可能な部材の重ね合わせ部分におけるかご戸２の開方向側（乗降口から離れる方向側）に、かご戸２の閉状態で曲げ変形可能な部材の変形を許す他の間隙を有して対向するかご戸側規制部１８を設けて構成することができる。   In the above embodiment, the first rubber plate 13 and the second rubber plate 15 have a thickness of about 0.5 mm. However, the present invention is not limited to this, and other bending deformable members are used. You can also. In any case, a second gap 14 is formed between the car door 2 and the car-side restricting portion 6 provided relative to the car door 2 in a closed state of the car door 2. In the closed state of the door 2, the first rubber plate 13 and the second rubber plate 15 are respectively placed on the car door 2 and the car-side restricting portion 6 so as to close the second gap 14 by overlapping the free ends. Such bending deformable members are attached alternately, and can be bent and deformed in the closed state of the car door 2 on the opening direction side (the direction side away from the entrance / exit) of the car door 2 in the overlapping portion of the bending deformable members. It is possible to provide a car door side restricting portion 18 that is opposed to the other car with another gap allowing deformation of the member.

さらに、上記の実施例では、かご戸に設けられた第一のブラケット８に第二のブラケット９を固定しかご戸側規制部１８を形成したが、これに限定するものではなく、例えば、第一のブラケット８を設けず、ボルト１７を利用してかご戸２の端面にかご戸側規制部１８を有する第二のブラケット９をかご戸２に固定しても良い。しかし、図示のように第二のゴム板１５をかご戸２に固定する固定部とかご戸側規制部１８を有する第二のブラケット９をかご戸２に固定する固定部とをそれぞれ別に設けた構成とすると、第一のゴム板１３および第二のゴム板１５が劣化したときの交換作業を簡単に行うことができる。 以上説明したように本発明のエレベーター装置は、かご戸２と、かご戸２に対して相対的に設けられた乗りかご側規制部６との間に、かご戸２の閉状態で第二間隙１４を形成し、かご戸２の閉状態で互いに自由端側を重ね合わせて第二の間隙１４を塞ぐように、かご戸２とかご戸２と対向する側板５ａとにそれぞれ第一のゴム板１３や第二のゴム板１５のような曲げ変形可能な部材を互い違いに取り付け、曲げ変形可能な部材の重ね合わせ部分における乗降口１ａと離れる方向側に、かご戸２の閉状態で曲げ変形可能な部材の弾性変形を許す間隙を有してかご戸側規制部１８を設けている。   Furthermore, in the above-described embodiment, the second bracket 9 is fixed to the first bracket 8 provided in the car door, but the car door side restricting portion 18 is formed. However, the present invention is not limited to this. Instead of providing one bracket 8, the second bracket 9 having the car door side regulating portion 18 on the end surface of the car door 2 may be fixed to the car door 2 using the bolt 17. However, as shown in the drawing, a fixing portion for fixing the second rubber plate 15 to the car door 2 and a fixing portion for fixing the second bracket 9 having the car door side regulating portion 18 to the car door 2 are provided separately. If comprised, the replacement | exchange operation | work when the 1st rubber plate 13 and the 2nd rubber plate 15 deteriorates can be performed easily. As described above, the elevator apparatus according to the present invention has the second gap between the car door 2 and the car-side regulating portion 6 provided relative to the car door 2 in the closed state of the car door 2. 14 is formed, and the first rubber plate is provided on each of the car door 2 and the side plate 5a facing the car door 2 so as to close the second gap 14 by overlapping the free end sides with the car door 2 closed. Bendable members such as 13 and the second rubber plate 15 are alternately attached, and can be bent and deformed in the closed state of the car door 2 in the direction away from the entrance 1a in the overlapping portion of the bendable members. The car door side restricting portion 18 is provided with a gap that allows elastic deformation of various members.

このような構成によれば、かご戸２の戸閉力を増強することなく、かご戸２によって存在してしまう第二の間隙１４を乗りかご１内の気圧変動に応じて密閉する気密装置を簡単に構成することができる。   According to such a configuration, the airtight device that seals the second gap 14 existing by the car door 2 according to the pressure fluctuation in the car 1 without increasing the door closing force of the car door 2. Easy to configure.
