PURPOSE: A mobile prefabricated building is provided to offer materials of expansion and contraction at the inner loading space of a high quality produced with inner shape steel and having a parallel hexahedron box structure. CONSTITUTION: Roof faces(52,54,56) are composed of base ceiling members(96,98) and an outer roof member(100). A truss(98) is hung by connecting the base ceiling member(96) at a truss hinge(102) constituted by connecting the truss at a ceiling crossbeam. In contracted state, the truss is inserted between the base ceiling member, the outer roof member, and the roof member defined as a parallel face and the base ceiling member. The low part of the roof member is hinged to an end girder(104) lengthened along the end of the base ceiling member for rotation hung of the roof member near an axis of the hinge of the roof member in parallel to the plane of the edge in the roof faces. To make an inclined roof as standing the truss at the construction(20), the roof member needs to be rotated to the direction of an arrow(106) near the hinge(101). In a vertical position, the truss supports the ceiling crossbeam vertically lengthened along a ceiling base part between the ends of the roof faces.
