Claims

[Claims for Utility Model Registration] (1) At least one end in the longitudinal direction is provided with a connecting center in the form of a horizontal axis, and is rotatably connected to other members via the connecting shaft provided at the connecting center. A bridge body frame that can be collapsed, a plurality of steps for getting on and off that are arranged in the longitudinal direction of this bridge body frame and each supported so that it can rotate around a horizontal axis, and the rotation of each step. An interlocking link that directly connects the entire step via an interlocking pin at a point different from the center, and a step at the end of the arrangement direction are rotated by equal amounts in the opposite direction to the rotational direction in which the bridge main frame is raised and lowered to maintain a horizontal posture. The step posture holding mechanism includes a drive wheel arranged around a connecting shaft and kept in a non-rotating state on the side of the other member, and a step posture holding mechanism that rotates around the center of rotation of the end step. A connecting bridge comprising a driven wheel arranged to rotate together with the outermost step, and a wheel interlocking means provided between the drive wheel and the driven wheel so as to interlock both wheels. (2) The connecting bridge according to claim 1, wherein the drive wheel, the driven wheel, and the wheel interlocking means are all gears.
