PROBLEM TO BE SOLVED: To provide a bearing device for securing a sufficient movable range, and for stably bearing a spanning structure.SOLUTION: A bearing structure 1 for bearing a connecting corridor C spanning a first structure A and a second structure B includes: a stationary side support structure 20 constituted of a rotary bearing device 200 disposed in the neighborhood of the middle in a width direction W of the connecting corridor C and omnidirectional bearing devices 230 disposed at both sides; and a movable side bearing structure 10 constituted of a uni-directional bearing device 100 disposed in the neighborhood of the middle of the width direction W and configured such that a slide plate of a sole plate of a lower shoe is more widely formed in a spanning direction L than the bearing of a base pot of an upper shoe, and belt-like omnidirectional bearing devices 130 disposed at both sides and configured such that the slide plate of the lower shoe is more widely formed in the spanning direction L and the width direction W than the bearing of the upper shoe and more widely formed in the spanning direction L than the width direction W. |
