Abstract: A passenger boarding bridge comprises a first walkway of an inner tunnel of adjacent tunnels of an extendable and retractable tunnel section; and a second walkway of an outer tunnel of the adjacent tunnels, the second walkway including a plurality of floor members which are arranged in the front-rear direction and are coupled to each other. The plurality of floor members are supported by an endless string-shaped member that is rotatable. A respective walkway surface of each walkway is at a predetermined equal height position. When the tunnel section is retracted, the string-shaped member of the second walkway is guided so that the floor members are moved down to an underside of the inner tunnel, and when the tunnel section is extended, the string-shaped member of the second walkway is guided so that the floor members are moved up from the underside of the inner tunnel.

Abstract: A passenger boarding bridge comprises: a walkway section which is provided at an outer tunnel of adjacent tunnels, and is movable between a walkway position and a non-walkway position located under the walkway position; and a plurality of rotary members arranged along the lengthwise direction of the outer tunnel, each of the plurality of rotary members being rotatable around a vertical rotation axis between a first rotation position at which the rotary member supports an end portion of the walkway section while at the walkway position and a second rotation position at which the rotary member does not support the end portion. In a case where at least one of adjacent rotary members of the plurality of rotary members is at the second rotation position, the adjacent rotary members partially overlap with each other when viewed in the width direction of the walkway section or in the vertical direction.
