ESCALATOR

PROBLEM TO BE SOLVED: To secure the courses of other passengers, even if passengers who slowly walk after they step down from an escalator exist, by constituting rails and moving handrails provided on both sides so as to be longer on only one side in the escalator provided with steps and the moving handrails traveling at substantially the same speed in the same direction. SOLUTION: At both of a boarding port 2 A to be a getting on port and an alighting port 2 B to be a getting off port, rails 3 and moving handrails 4 are made longer on only one side. Because almost passengers who slowly walk normally use the moving handrails 4, they walk in a state that they grasp the moving handrail 4 as it is so long as the moving handrails 4 exist also after they get off the steps of an escalator. Namely, passengers who slowly walk can be guided in a fixed direction and can be prevented from hanging around over the full width of the getting off port. Therefore, the courses of passengers who step down succeeding to the passengers who slowly walk and are normally in a hurry can be sufficiently secured.
