Furthermore, each first brace 17 is arranged in the region of the door frame 10 of the car door device 8 as shown in FIG. 3 when viewed from above.
　各第１筋交い１７は、第１端部１７ａと、第２端部１７ｂと、第１端部１７ａ及び第２端部１７ｂ間を繋ぐ棒状部１７ｃとを有している。この例では、棒状部１７ｃに繋がったＬ字状の接続金具が第１端部１７ａ及び第２端部１７ｂとしてそれぞれ用いられている。また、この例では、第１端部１７ａ及び第２端部１７ｂのそれぞれに対する棒状部１７ｃの位置が棒状部１７ｃの長手方向へ調整可能になっている。これにより、各第１筋交い１７の長さが調整可能になっている。 Each first bracing 17 has a first end portion 17a, a second end portion 17b, and a rod-like portion 17c that connects the first end portion 17a and the second end portion 17b. In this example, L-shaped connection fittings connected to the rod-like portion 17c are used as the first end portion 17a and the second end portion 17b, respectively. In this example, the position of the rod-shaped portion 17c with respect to each of the first end portion 17a and the second end portion 17b can be adjusted in the longitudinal direction of the rod-shaped portion 17c. Thereby, the length of each 1st bracing 17 can be adjusted.
　各第１筋交い１７の第１端部１７ａは、各取付部材１６の中間部に個別に接続されている。各第１筋交い１７の第２端部１７ｂは、第１端部１７ａからかご出入口４の間口方向へ離れた位置で、かつ第１端部１７ａよりも高い位置で上枠６の出入口側端部６ａに接続されている。この例では、各第１筋交い１７の第２端部１７ｂがかご出入口４の間口方向における一対の取付部材１６の間の位置で出入口側端部６ａに接続されている。これにより、各第１筋交い１７は、上枠６の出入口側端部６ａから下方に向かって取付部材１６に近づく方向へ傾斜している。この例では、第１端部１７ａが取付部材１６にボルトで接続され、第２端部１７ｂが出入口側端部６ａにボルトで接続されている。 The first end portion 17a of each first brace 17 is individually connected to the intermediate portion of each attachment member 16. The second end portion 17b of each first brace 17 is located at a position away from the first end portion 17a toward the front entrance of the car doorway 4 and at a position higher than the first end portion 17a, on the entrance / exit side end portion of the upper frame 6 6a. In this example, the second end portion 17 b of each first brace 17 is connected to the entrance / exit side end portion 6 a at a position between the pair of attachment members 16 in the entrance direction of the car entrance 4. Thereby, each 1st bracing 17 inclines in the direction which approaches the attachment member 16 toward the downward direction from the entrance-and-exit side edge part 6a of the upper frame 6. As shown in FIG. In this example, the first end portion 17a is connected to the attachment member 16 with a bolt, and the second end portion 17b is connected to the entrance / exit side end portion 6a with a bolt.
　一対の第２筋交い１８のそれぞれは、かご１の奥行き方向における一対の取付部材１６の強度を高めるための第２補強部材である。一対の第２筋交い１８は、かご出入口４の間口方向におけるかご室２の両側に配置されている。また、各第２筋交い１８は、かご室２の側面よりも外側に配置されている。さらに、各第２筋交い１８は、かご１の幅方向に直交する２つの仮想平面上、即ちかご室２の側面と平行な２つの仮想平面上に個別に配置されている。 Each of the pair of second braces 18 is a second reinforcing member for increasing the strength of the pair of attachment members 16 in the depth direction of the car 1. The pair of second braces 18 are disposed on both sides of the car room 2 in the front-and-rear direction of the car doorway 4. Each second brace 18 is disposed outside the side surface of the cab 2. Further, each second brace 18 is individually arranged on two virtual planes orthogonal to the width direction of the car 1, that is, on two virtual planes parallel to the side surface of the car room 2.
　各第２筋交い１８は、第３端部１８ａと、第４端部１８ｂとを有する棒状部材である。各第２筋交い１８の第３端部１８ａは、各取付部材１６の中間部に個別に接続されている。各第２筋交い１８の第４端部１８ｂは、各縦柱側端部６ｂに個別に接続されている。各第２筋交い１８の第４端部１８ｂの位置は、第３端部１８ａからかご１の奥行き方向へ離れた位置で、かつ第３端部１８ａよりも高い位置になっている。これにより、各第２筋交い１８は、図４に示すように、上枠６の縦柱側端部６ｂから下方に向かって取付部材１６に近づく方向へ傾斜している。この例では、各第２筋交い１８の第４端部１８ｂの位置がかご１の奥行き方向における取付部材１６と縦柱７との間の位置になっている。また、この例では、第３端部１８ａが取付部材１６にボルトで接続され、第４端部１８ｂが縦柱側端部６ｂにボルトで接続されている。 Each second brace 18 is a rod-shaped member having a third end 18a and a fourth end 18b. The third end portion 18 a of each second brace 18 is individually connected to the intermediate portion of each mounting member 16. The fourth end 18b of each second brace 18 is individually connected to each vertical column side end 6b. The position of the fourth end 18b of each second brace 18 is a position away from the third end 18a in the depth direction of the car 1 and higher than the third end 18a. Thereby, each 2nd bracing 18 inclines in the direction which approaches the attachment member 16 toward the downward direction from the vertical column side edge part 6b of the upper frame 6, as shown in FIG. In this example, the position of the fourth end 18 b of each second brace 18 is a position between the attachment member 16 and the vertical column 7 in the depth direction of the car 1. In this example, the third end portion 18a is connected to the mounting member 16 with a bolt, and the fourth end portion 18b is connected to the vertical column side end portion 6b with a bolt.
　このようなエレベータのドア支持装置９では、上枠６から下方へ突出した一対の取付部材１６にかごドア装置８が取り付けられている。また、一対の第１筋交い１７のそれぞれの第１端部１７ａが一対の取付部材１６に個別に接続され、一対の第１筋交い１７のそれぞれの第２端部１７ｂが上枠６に接続されている。このため、各取付部材１６の強度を小さくしても、一対の第１筋交い１７のそれぞれによって各取付部材１６を変形しにくくすることができる。例えば、かごドア１２の移動の反転時の加減速によって各取付部材１６に荷重が加わる場合にも、各取付部材１６を変形しにくくすることができ、各取付部材１６の強度の信頼性を確保することができる。これにより、各取付部材１６の強度を小さくすることができ、ドア支持装置９の小型化及び軽量化を図ることができる。従って、かご１の全体の軽量化を図ることができる。また、かご室２の天井の高さが異なる複数のかご１に対しても、例えば各取付部材１６に対するドアフレーム１０の取付位置を調整することにより、かご出入口４に対するドアフレーム１０の高さ方向の位置を一定にすることができる。 In such an elevator door support device 9, the car door device 8 is attached to a pair of attachment members 16 protruding downward from the upper frame 6. Further, the first end portions 17a of the pair of first braces 17 are individually connected to the pair of attachment members 16, and the second end portions 17b of the pair of first braces 17 are connected to the upper frame 6. Yes. For this reason, even if the strength of each attachment member 16 is reduced, each attachment member 16 can be made difficult to deform by each of the pair of first braces 17. For example, even when a load is applied to each mounting member 16 due to acceleration / deceleration at the time of reversal of the movement of the car door 12, each mounting member 16 can be made difficult to deform, and the strength reliability of each mounting member 16 is ensured. can do. Thereby, the intensity | strength of each attachment member 16 can be made small, and size reduction and weight reduction of the door support apparatus 9 can be achieved. Accordingly, the overall weight of the car 1 can be reduced. Further, for a plurality of cars 1 having different ceiling heights in the car room 2, for example, by adjusting the mounting position of the door frame 10 with respect to each mounting member 16, the height direction of the door frame 10 with respect to the car doorway 4. The position of can be made constant.
　さらに、一対の取付部材１６のそれぞれの長さを短くすることができる。このため、ドアフレーム１０をかご１に設置するときに、一対の取付部材１６とドアフレーム１０とを一体にしたユニットを昇降路内に搬入することができる。これにより、かご１に対するドアフレーム１０の設置作業の負担を軽くすることができる。即ち、一対の取付部材１６をかご１に取り付けた後にドアフレーム１０を一対の取付部材１６に取り付ける場合、ドアフレーム１０がかご室２の天井よりもかなり下方に配置されるため、かご室２の天井に乗った作業者からはドアフレーム１０の取付位置にアクセスしづらい状態になる。これに対して、実施の形態１では、ドアフレーム１０に一対の取付部材１６を予め取り付けておくことができるため、かご室２の天井に乗った作業者がドアフレーム１０の取付位置にアクセスせずにドアフレーム１０を容易に設置することができる。 Furthermore, the length of each of the pair of attachment members 16 can be shortened. For this reason, when installing the door frame 10 in the cage | basket | car 1, the unit which united a pair of attachment member 16 and the door frame 10 can be carried in in a hoistway. Thereby, the burden of the installation work of the door frame 10 with respect to the cage | basket | car 1 can be lightened. That is, when the door frame 10 is attached to the pair of attachment members 16 after attaching the pair of attachment members 16 to the car 1, the door frame 10 is arranged considerably below the ceiling of the car room 2. It is difficult for an operator on the ceiling to access the mounting position of the door frame 10. In contrast, in the first embodiment, since the pair of attachment members 16 can be attached in advance to the door frame 10, an operator on the ceiling of the cab 2 can access the attachment position of the door frame 10. Therefore, the door frame 10 can be easily installed.
　また、一対の第１筋交い１７は、上から見たとき、かごドア装置８のドアフレーム１０の領域内に配置されている。このため、一対の第１筋交い１７をかご１に設置したことによってかご１全体の水平方向のスペースが拡大してしまうことを防止することができる。 Also, the pair of first braces 17 are arranged in the region of the door frame 10 of the car door device 8 when viewed from above. For this reason, it can prevent that the space of the horizontal direction of the cage | basket | car 1 whole will be expanded by installing a pair of 1st bracing 17 in the cage | basket | car 1. FIG.
　また、一対の第２筋交い１８のそれぞれの第４端部１８ｂの位置は、第３端部１８ａからかご１の奥行き方向へ離れた位置になっている。このため、かご１の奥行き方向における各取付部材１６の強度を各第２筋交い１８によって確保することができる。例えば、乗客がかごドア１２を押して各取付部材１６に荷重が加わる場合にも、各取付部材１６を変形しにくくすることができる。これにより、各取付部材１６の強度の信頼性の向上をさらに確実に図ることができる。 Further, the position of the fourth end 18b of each of the pair of second braces 18 is a position away from the third end 18a in the depth direction of the car 1. For this reason, the strength of each attachment member 16 in the depth direction of the car 1 can be ensured by each second brace 18. For example, even when a passenger pushes the car door 12 and a load is applied to each attachment member 16, it is possible to make each attachment member 16 difficult to deform. Thereby, the improvement of the reliability of the strength of each mounting member 16 can be further ensured.
　また、各第１筋交い１７の長さが調整可能になっている。このため、かご出入口４の間口方向におけるかごドア装置８の位置の微調整を各第１筋交い１７の長さの調整によって行うことができる。さらに、各第１筋交い１７は、かご室２の正面よりも乗場側に配置されている。このため、各第１筋交い１７の長さの調整を乗場から容易に行うことができる。 Also, the length of each first brace 17 can be adjusted. For this reason, fine adjustment of the position of the car door device 8 in the frontage direction of the car doorway 4 can be performed by adjusting the length of each first brace 17. Furthermore, each 1st bracing 17 is arrange | positioned rather than the front of the cab 2 at the landing side. For this reason, the length of each first brace 17 can be easily adjusted from the landing.
　なお、上記の例では、各第１筋交い１７の第２端部１７ｂが上枠６の出入口側端部６ａに接続されている。しかし、各第１筋交い１７の第２端部１７ｂをドアフレーム１０に接続してもよい。このようにしても、かご１の幅方向における各取付部材１６の強度を各第１筋交い１７によって確保することができる。 In the above example, the second end 17b of each first brace 17 is connected to the entrance / exit side end 6a of the upper frame 6. However, the second end 17 b of each first brace 17 may be connected to the door frame 10. Even in this way, the strength of each attachment member 16 in the width direction of the car 1 can be ensured by each first brace 17.
　また、上記の例では、各第２筋交い１８の第４端部１８ｂが上枠６に接続されている。しかし、各第２筋交い１８の第４端部１８ｂを縦柱７に接続してもよい。このようにしても、かご１の奥行き方向における各取付部材１６の強度を各第２筋交い１８によって確保することができる。 In the above example, the fourth end 18 b of each second brace 18 is connected to the upper frame 6. However, the fourth end 18 b of each second brace 18 may be connected to the vertical column 7. Even in this way, the strength of each attachment member 16 in the depth direction of the car 1 can be ensured by each second brace 18.
　また、上記の例では、第１筋交い１７の第１端部１７ａが取付部材１６にボルトで接続され、第１筋交い１７の第２端部１７ｂが上枠６の出入口側端部６ａにボルトで接続されている。しかし、取付部材１６に固定されたフック部材に第１端部１７ａを掛けることにより、取付部材１６に第１端部１７ａを接続してもよい。また、出入口側端部６ａに固定されたフック部材に第２端部１７ｂを掛けることにより、出入口側端部６ａに第２端部１７ｂを接続してもよい。このようにすれば、上枠６及び取付部材１６に対する第１筋交い１７の接続作業の負担の軽減化を図ることができる。 In the above example, the first end 17 a of the first brace 17 is connected to the mounting member 16 with a bolt, and the second end 17 b of the first brace 17 is bolted to the entrance / exit side end 6 a of the upper frame 6. It is connected. However, the first end 17 a may be connected to the mounting member 16 by hanging the first end 17 a on the hook member fixed to the mounting member 16. Alternatively, the second end 17b may be connected to the entrance / exit side end 6a by hooking the second end 17b on the hook member fixed to the entrance / exit side end 6a. In this way, it is possible to reduce the burden of connecting the first brace 17 to the upper frame 6 and the mounting member 16.
　また、上記の例では、一対の第１筋交い１７のそれぞれの第１端部１７ａが一対の取付部材１６に個別に接続されている。しかし、一対の第１筋交い１７のそれぞれの第１端部１７ａをかごドア装置８のドアフレーム１０に接続してもよい。このようにしても、各第１筋交い１７の補強によって各取付部材１６の強度を小さくすることができ、ドア支持装置９の小型化及び軽量化を図ることができる。この場合、一方の第１筋交い１７の第１端部１７ａは他方の取付部材１６よりも一方の取付部材１６に近い位置でドアフレーム１０に接続され、他方の第１筋交い１７の第１端部１７ａは一方の取付部材１６よりも他方の取付部材１６に近い位置でドアフレーム１０に接続される。 In the above example, the first end portions 17a of the pair of first braces 17 are individually connected to the pair of attachment members 16. However, the first end portions 17 a of the pair of first braces 17 may be connected to the door frame 10 of the car door device 8. Even if it does in this way, the intensity | strength of each attachment member 16 can be made small by reinforcement of each 1st bracing 17, and size reduction and weight reduction of the door support apparatus 9 can be achieved. In this case, the first end 17 a of one first brace 17 is connected to the door frame 10 at a position closer to the one attachment member 16 than the other attachment member 16, and the first end of the other first brace 17 17 a is connected to the door frame 10 at a position closer to the other mounting member 16 than to the one mounting member 16.
　また、上記の例では、一対の取付部材１６のそれぞれの下端部がかご１の下部よりも上方に配置されている。しかし、一対の取付部材１６のそれぞれの下端部をかご１の下部に接続してもよい。即ち、上下方向にそれぞれ延びる一対の取付部材１６を上枠６の出入口側端部６ａと下枠５との間にそれぞれ接続してもよい。このようにすれば、上枠６のねじり剛性が弱い場合でも、一対の取付部材１６によって上枠６を補強することができる。この場合、各取付部材１６の長手方向の引張強度及び圧縮強度によって上枠６のねじり剛性を補強することができることから、各取付部材１６の太さを細くすることができる。これにより、かご１の全体としては軽量化を図ることができる。 In the above example, the lower end portions of the pair of attachment members 16 are disposed above the lower portion of the car 1. However, the lower end portions of the pair of attachment members 16 may be connected to the lower portion of the car 1. That is, a pair of attachment members 16 extending in the vertical direction may be connected between the entrance / exit side end 6 a of the upper frame 6 and the lower frame 5. In this way, even when the torsional rigidity of the upper frame 6 is weak, the upper frame 6 can be reinforced by the pair of attachment members 16. In this case, since the torsional rigidity of the upper frame 6 can be reinforced by the tensile strength and compressive strength in the longitudinal direction of each mounting member 16, the thickness of each mounting member 16 can be reduced. Thereby, weight reduction can be achieved as the whole car 1.

The second restricting member 36 is disposed on the inner side in the width direction of the car 1 than the first restricting member 35. The second restricting member 36 is formed with a receiving surface orthogonal to the width direction of the car 1. The second restricting member 36 receives the buffer member 38 b of the first restricting member 35 on the receiving surface of the second restricting member 36. The pair of steady rest mechanisms 34 suppresses the displacement of the car room 2 in the width direction with respect to the car frame 3 by receiving the first restricting member 35 by the second restricting member 36. Other configurations are the same as those in the first embodiment.
　このようなエレベータのドア支持装置９では、一対のアーム部材３２のそれぞれから下方へ突出した一対の取付部材１６にかごドア装置８が取り付けられている。また、一対の第１筋交い１７のそれぞれの第１端部１７ａが一対の取付部材１６に個別に接続され、一対の第１筋交い１７のそれぞれの第２端部１７ｂがドアフレーム１０に接続されている。このため、各取付部材１６の強度を各第１筋交い１７によって確保することができ、各取付部材１６の小型化及び軽量化を図ることができる。これにより、かご１の全体の軽量化を図ることができる。また、実施の形態１と同様に、かご出入口４に対するドアフレーム１０の高さ方向の位置を一定にすることができる。さらに、一対の取付部材１６のそれぞれの長さを短くすることができるため、かご１に対するドアフレーム１０の設置作業の負担を軽くすることができる。 In such an elevator door support device 9, the car door device 8 is attached to a pair of attachment members 16 protruding downward from each of the pair of arm members 32. In addition, the first end portions 17 a of the pair of first bracings 17 are individually connected to the pair of attachment members 16, and the second end portions 17 b of the pair of first bracing 17 are connected to the door frame 10. Yes. For this reason, the strength of each attachment member 16 can be secured by each first brace 17, and each attachment member 16 can be reduced in size and weight. Thereby, the weight reduction of the whole cage | basket | car 1 can be achieved. Further, as in the first embodiment, the position of the door frame 10 in the height direction with respect to the car doorway 4 can be made constant. Furthermore, since each length of a pair of attachment member 16 can be shortened, the burden of the installation operation | work of the door frame 10 with respect to the cage | basket | car 1 can be lightened.
　また、一対のアーム部材３２のそれぞれには、かご枠３に対するかご室２の幅方向の変位を抑制する振れ止め機構３４が設けられている。このため、例えばかごドア装置８の動作による荷重が各取付部材１６に加わった場合でも、各取付部材１６及び各アーム部材３２を変形しにくくすることができる。これにより、ドア支持装置９の強度の信頼性の向上をさらに図ることができる。 Further, each of the pair of arm members 32 is provided with an anti-sway mechanism 34 that suppresses displacement in the width direction of the car room 2 with respect to the car frame 3. For this reason, even when the load by operation | movement of the car door apparatus 8 is added to each attachment member 16, for example, each attachment member 16 and each arm member 32 can be made difficult to deform | transform. Thereby, the reliability of the strength of the door support device 9 can be further improved.
　なお、上記の例では、各第１筋交い１７の第２端部１７ｂがドアフレーム１０に接続されている。しかし、各第１筋交い１７の第２端部１７ｂを各アーム部材３２の出入口側端部３２ａに個別に接続してもよい。この場合、一対の第１筋交い１７は、かご１の奥行き方向に沿って見たとき、互いに交差して配置される。このようにしても、かご１の幅方向における各取付部材１６の強度を各第１筋交い１７によって確保することができる。 In the above example, the second end 17 b of each first brace 17 is connected to the door frame 10. However, the second end 17 b of each first brace 17 may be individually connected to the entrance / exit side end 32 a of each arm member 32. In this case, the pair of first braces 17 are arranged so as to cross each other when viewed along the depth direction of the car 1. Even in this way, the strength of each attachment member 16 in the width direction of the car 1 can be ensured by each first brace 17.
　また、上記の例では、各第２筋交い１８の第４端部１８ｂが縦柱７に接続されている。しかし、各第２筋交い１８の第４端部１８ｂをアーム部材３２に接続してもよい。このようにしても、かご室２の奥行き方向における各取付部材１６の強度を各第２筋交い１８によって確保することができる。 In the above example, the fourth end 18 b of each second brace 18 is connected to the vertical column 7. However, the fourth end 18 b of each second brace 18 may be connected to the arm member 32. Even in this way, the strength of each attachment member 16 in the depth direction of the car room 2 can be ensured by each second brace 18.
　また、上記の例では、第１筋交い１７の第１端部１７ａが取付部材１６にボルトで接続され、第１筋交い１７の第２端部１７ｂがドアフレーム１０にボルトで接続されている。しかし、取付部材１６に固定されたフック部材に第１端部１７ａを掛けることにより、取付部材１６に第１端部１７ａを接続してもよい。また、ドアフレーム１０に固定されたフック部材に第２端部１７ｂを掛けることにより、ドアフレーム１０に第２端部１７ｂを接続してもよい。このようにすれば、ドアフレーム１０及び取付部材１６に対する第１筋交い１７の接続作業の負担の軽減化を図ることができる。 In the above example, the first end 17a of the first brace 17 is connected to the mounting member 16 with a bolt, and the second end 17b of the first brace 17 is connected to the door frame 10 with a bolt. However, the first end 17 a may be connected to the mounting member 16 by hanging the first end 17 a on the hook member fixed to the mounting member 16. Alternatively, the second end 17 b may be connected to the door frame 10 by hanging the second end 17 b on a hook member fixed to the door frame 10. In this way, it is possible to reduce the burden of connecting the first brace 17 to the door frame 10 and the mounting member 16.
　また、上記の例では、第１規制部材３５がアーム部材３２に固定され、第２規制部材３６がかご室２に固定されている。しかし、第１規制部材３５をかご室２に固定し、第２規制部材３６をアーム部材３２に固定してもよい。 In the above example, the first restricting member 35 is fixed to the arm member 32, and the second restricting member 36 is fixed to the cab 2. However, the first restriction member 35 may be fixed to the cab 2 and the second restriction member 36 may be fixed to the arm member 32.
　また、上記の例では、一対の第１筋交い１７のそれぞれの第１端部１７ａが一対の取付部材１６に個別に接続されている。しかし、一対の第１筋交い１７のそれぞれの第１端部１７ａを各アーム部材３２の出入口側端部３２ａに個別に接続してもよい。このようにしても、各第１筋交い１７の補強によって各取付部材１６の強度を小さくすることができ、ドア支持装置９の小型化及び軽量化を図ることができる。 In the above example, the first end portions 17a of the pair of first braces 17 are individually connected to the pair of attachment members 16. However, the first end portions 17 a of the pair of first braces 17 may be individually connected to the entrance / exit side end portions 32 a of the arm members 32. Even if it does in this way, the intensity | strength of each attachment member 16 can be made small by reinforcement of each 1st bracing 17, and size reduction and weight reduction of the door support apparatus 9 can be achieved.
　また、上記の例では、一対の取付部材１６のそれぞれの下端部がかご１の下部よりも上方に配置されている。しかし、一対の取付部材１６のそれぞれの下端部をかご１の下部に接続してもよい。即ち、上下方向にそれぞれ延びる一対の取付部材１６を各アーム部材３２と下枠５との間にそれぞれ接続してもよい。このようにすれば、各アーム部材３２のねじり剛性が弱い場合でも、一対の取付部材１６によって各アーム部材３２を補強することができる。この場合、各取付部材１６の長手方向の引張強度及び圧縮強度によって各アーム部材３２のねじり剛性を補強することができることから、各取付部材１６の太さを細くすることができる。これにより、かご１の全体としては軽量化を図ることができる。 In the above example, the lower end portions of the pair of attachment members 16 are disposed above the lower portion of the car 1. However, the lower end portions of the pair of attachment members 16 may be connected to the lower portion of the car 1. That is, a pair of attachment members 16 extending in the vertical direction may be connected between each arm member 32 and the lower frame 5. In this way, each arm member 32 can be reinforced by the pair of attachment members 16 even when the torsional rigidity of each arm member 32 is weak. In this case, since the torsional rigidity of each arm member 32 can be reinforced by the tensile strength and compressive strength in the longitudinal direction of each mounting member 16, the thickness of each mounting member 16 can be reduced. Thereby, weight reduction can be achieved as the whole car 1.
　また、各上記実施の形態では、一対の第２筋交い１８が各取付部材１６に接続されている。しかし、一対の第２筋交い１８はなくてもよい。一対の第２筋交い１８がなくても、かご１の幅方向における各取付部材１６の強度を各第１筋交い１７によって確保することができる。 Further, in each of the above-described embodiments, a pair of second braces 18 are connected to each mounting member 16. However, the pair of second braces 18 may not be present. Even without the pair of second braces 18, the strength of the mounting members 16 in the width direction of the car 1 can be secured by the first braces 17.
　また、各上記実施の形態では、各第１筋交い１７の長さが調整可能になっている。しかし、各第１筋交い１７の長さが調整不可能で一定であってもよい。 In each of the above embodiments, the length of each first brace 17 can be adjusted. However, the length of each first brace 17 may not be adjustable and may be constant.
