検作業の間、安定したセット状態を維持できる。Also, when the film body 8a is set at the entrance / exit portion, the elastic body
Since 8c 1 ~8c 4 elastic force through the membrane body 8a is held, robust to disturbances of wind pressure, etc., it is also suitable when using strong maintenance work such as subway passenger conveyor which wind generated Therefore, the stable set state can be maintained during the maintenance and inspection work without the film body 8a peeling off due to the wind.
また、膜体8aに「作業中」の注意文字を表示してること
から、保守員以外の第３者に対して、マンコンベア方向
への進入禁止の状態にあることを確実に知らせることが
できる。Further, since the caution character "working" is displayed on the film body 8a, it is possible to reliably notify a third person other than the maintenance staff that the entry in the direction of the man conveyor is prohibited. .

の能率を向上させることができる。According to the present invention, each of the first locking portion attached to the upper side of the film body and the second locking portion attached to the lower side of the film body is attached to the corresponding handrail to attach the man. It can be easily set at the entrance / exit of the conveyor, and since the main part is a membrane, it is light and easy to carry,
As a result, the efficiency of maintenance and inspection work of the man conveyor can be improved as compared with the conventional case.
