PROBLEM TO BE SOLVED: To improve the durability of a floor coupling two vehicles, capable of following relative displacement of both vehicles when turning a curve, having traverse undulations for allowing passengers to move between both vehicles by walking on a top face of the floor, reinforcing the undulations by metal blades extending in a traverse direction, and providing an elastmer reinforcing structure portion between the blades of each pair of the metal blades. SOLUTION: Traverse dimension of each elastomer reinforcing portion is made 2L<SB>0</SB>, and each elastomer reinforcing portion is made from at least one elastomer piece 30. The elastomer reinforcing portion between at least one pair of the metal blades 15 adjacent to a longitudinal end 12, 14 of the floor is made from at least two elastomer pieces 30 separated from the longitudinal plane symmetry of the floor that is a plane parallel to the longitudinal direction.
