LONGITUDINAL CONNECTION PART

PROBLEM TO BE SOLVED: To provide a longitudinal connection part which is usable as a passage between a first passage surface and a second passage surface that are adjacent to one another and usable as a pedestrian passage, and is capable of varying a distance in a longitudinal direction between the first passage surface and the second passage surface.SOLUTION: The longitudinal connection part includes a plurality of transverse slats 4 which have a substantially planar upper surface and are attached to one another, each of the transverse slats 4 is attached to the adjacent slat 4 by a pivot part and is made rotatable by the pivot part, and continuity of an upper surface of a longitudinal connection member 1 is maintained. The transverse slat 4 is supported by a support curved surface, a first support surface and a second support surface, and some of the transverse slats 4 are hidden under a first passage surface 2 by relative rotation of the transverse slats 4 to one another by the pivot part according to a distance between the first passage surface 2 and a second passage surface 3 below the upper surface.
