Abstract
It is an object to provide a boarding bridge that can guide passengers to a predetermined gangway at the distal end and in which safety can be improved. A boarding bridge is provided which includes a proximal-end tunnel and a distal-end tunnel telescopically fitted together and capable of relative movement in a longitudinal direction; and a traveling unit mounted at the lower part of a movable leg that supports the distal-end tunnel and moving the movable leg by traveling; wherein the traveling unit includes a pair of traveling devices disposed with a certain distance therebetween in the widthwise direction of the distal-end tunnel, the traveling devices each having an axle rotatable about a vertically extending axis, a plurality of tires rotatably mounted to the axle with a certain distance therebetween, and a traveling motor that rotationally drives the axle; and a rotation synchronizing member that synchronizes the rotation angles of the axles in the pair of traveling devices.
