ABSTRACT:
An elevator is provided to prevent a tail cord from being projected out of a tail-cord duct under the influence of air current flowing in the tail-cord duct. The tail-cord duct is formed along an elevating space in which a passenger car moves up and down. The tail-cord duct is provided, along the elevating space, with an opening that opens it. An arm part fixed to the passenger car is introduced into the tail-cord duct. In the tail-cord duct, a tail cord is suspended from the arm part. In plan view of the tail-cord duct, a portion of the arm part for suspending the tail cord is shifted from the opening in a duct-width direction of the duct.
