Passenger transfer device

The invention provides a passenger transfer device, capable of not only realizing light weight of a frame and increasing the production rate of the frame, but also conveniently performing the disassembly of the frame. In the passenger transfer device, the circumference of the steel plate is bent an L-shaped cross section to form a plurality of side frame units comprising upper edges (11a) formingupper chord parts, lower edges (11b) forming lower chord parts, connection edges (11c) forming connection parts and side surfaces (11d) enclosed by the edges and the connection edges (11c) of the adjacent side frame units are mutually fixed together by connection components (13) and a longitudinal component (15) are fixed on the upper edges (11a) and the lower edges (11b) and the side surfaces (11d) of the steel plate, thus left, right side frames (11A,11B) are formed and the longitudinal components (15) of the left, right side frames (11A,11B) are connected together by cross beams (12A,12B).
