照）。Since the landing escalator has a curved portion in the middle of the main body, the running resistance of the step (2) and the handrail belt (6) is generated more in this curved portion than in the case of a general escalator. Therefore, the tension of the handrail belt (6) during driving becomes higher than that in a general escalator,
Handrail belt (6) at the concavely curved parts (B) and (C)
Is easily released upward. Explaining an example during the ascending operation in which a large load is applied, in the concavely curved portion (C) of the handrail belt (6), it occurs in the outward handrail belt (6a) as compared with the concavely curved portion (B). Tension becomes stronger. Therefore, in the region (C), a strong force acts that the outward handrail belt (6a) floats in the direction of the arrow (D) in FIG. Therefore, even if the jaw of the handrail belt (6a) does not soften due to material fatigue, the handrail belt (6a) may be detached from the guide portion (5) only by the tension as shown by the broken line (E) in FIGS. 5 and 6. easy. In the worst case, even the part shown by the broken line (F) will come off, and the handrail belt (6) will stop even though the step (2) is moving, and even passengers will This may result in a fall accident. For this reason, conventionally, a detector (10) for detecting the disengagement of the handrail belt (6) is provided between the guide portions (5), and means for stopping the escalator device when the disengagement of the handrail belt (6) is detected. (See Japanese Utility Model Publication No. 51-27591).

溝部（21a）を嵌装して装着している。The present invention will be described below with reference to illustrated embodiments. FIG. 1 is a vertical cross-sectional view of a passenger conveyor according to an embodiment of the present invention. An endless handrail belt (6) is generally formed by laminating canvas or the like with synthetic rubber as a core material, and forming the core thereof. This is a conventionally known one in which a steel strip (20) as a flexible ridge of a magnetic material, which includes a steel wire, a steel rope, and the like, is embedded between the layers of the material. On the other hand, between the guides (5) and (5) made of a non-magnetic material of the holding frame (4), there is a magnetic force that attracts the steel strip (20) and overcomes the levitation force of the handrail belt (6), and has a groove portion. (twenty one
a) A permanent magnet (21) (third part) as a magnetic body formed
The groove portion (21a) is fitted and attached to a protrusion (5a) protruding inward of the guide portion.
このため、運転中、手摺ベルト（６）に高負荷がかか
り、過大な張力が発生して、ガイド部（５）から浮上す
る力が生じても、永久磁石（21）により、離脱が阻止さ
れる。Therefore, during operation, even if a high load is applied to the handrail belt (6) and an excessive tension is generated to generate a force to levitate from the guide portion (5), the permanent magnet (21) prevents the detachment. It
なお、上記実施例では上記永久磁石（21）をガイド部

突部（5a）に嵌装して取付ける構造としているが、これ
に限られるものではなく、ねじ締めなど他の固着方法を
用いてもよいことはもちろんである。In the above embodiment, the permanent magnet (21) is attached to the guide portion (5), but the groove (21a) is fitted in the protrusion (5a) of the guide portion (5). Of course, the fixing method is not limited to this, and other fixing methods such as screw tightening may be used.
また、第４図に示すように、永久磁石（21）を分割し
て、ガイド部（５）間に配置し、各種の外形寸法を備え
たエスカレータ装置の湾曲部に対応させてもよいのはい
うまでもない。Further, as shown in FIG. 4, the permanent magnet (21) may be divided and placed between the guide portions (5) to correspond to the curved portion of the escalator device having various outer dimensions. Needless to say.
さらに、上記実施例では磁性体として永久磁石（21）

おいては、休止中に手摺ベルトが硬化しているため起動
抵抗が増すので、このような構成が望ましい。なお、ガ
イド部（５）は非磁性材料で製作することが望ましい。Furthermore, in the above embodiment, the permanent magnet (21) is used as the magnetic material.
However, the present invention is not limited to this, and it may be configured by an electromagnet so that it is magnetized only while the escalator is in operation, and the energizing circuit is formed so that it is magnetized immediately after startup, and the startup resistance of the escalator is changed. It can be reduced. This is particularly preferable in an escalator installed in a cold region because the handrail belt is hardened during rest and the starting resistance increases. The guide portion (5) is preferably made of a non-magnetic material.
上記実施例では、鋼帯（20）は手摺ベルト（６）内部
に埋込んでいるが、手摺ベルト（６）内周面に貼着して
もよいのはもちろんであり、鋼線、鋼索など可撓條体に
してもよい。Although the steel strip (20) is embedded in the handrail belt (6) in the above-mentioned embodiment, it is needless to say that the steel strip (20) may be attached to the inner peripheral surface of the handrail belt (6), such as steel wire and steel rope. You may make it a flexible body.
また、本発明はエスカレータについて説明したが、湾
曲部を有する動く歩道等にも適用可能である。Further, although the present invention has been described with respect to the escalator, it can be applied to a moving sidewalk having a curved portion.

の高いマンコンベアを得られる効果がある。As described above, according to the present invention, the steel strip is provided on the inner side of the handrail belt, and the magnetic body that attracts the handrail belt is mounted between the pair of guide portions, so that the handrail belt can be separated from the guide portion. There is an effect that it can be prevented and a highly safe passenger conveyor can be obtained.
