摘要： PURPOSE:To improve the rigidity of a carbody and reduce its weight by arranging light alloy front face materials on both surfaces of a core material, providing connecting materials on the outer peripheral ends of the core material and the front face materials, and between both the front face materials, and constituting the car body by boards obtained by brazing the above materials. CONSTITUTION:In an aluminum alloy carbody structure 1 consisting of an underframe 2, side body structures 3, a roof body structure 4, and end body structures 5, the underframe 2 is composed of side beams 6 arranged on both ends across the vehicle body width along the longitudinal direction of the vehicle body, a cross beam 7 laid-installed between the side beams 6, 6, and a floor board 8 lined-installed on the side beam. In this case, for example, with the floor board 8 constituting the body structure, light alloy front face materials 9, 9 are arranged on both surfaces of a honeycomb core material 10, connecting members 11a are arranged between both the front face materials 9, 9 on the outer peripheral ends of the square front face material 9, and these materials are brazed and joined to form a board member. Besides, at least the peripheral parts of the openings such as side window, side entrances, end entrances are constituted by light alloy extruded sections.

摘要： PURPOSE:To provide a roof body structure having a structure capable of sufficiently withstanding pressure in accordance with the speed up of vehicles, and provided with a high reliability in its strength. CONSTITUTION:A notch hole 39 is provided through a long beam web 36 at the position at which an underflange 33f of a rafter and the web 36 of a long beam 32 are joined to each other. Thus, a structure in which both welding 38 from the rafter side and welding from the long beam side through the notch hole 39 can be performed, is obtained. A disadvantage in that the strength of a weld-junction between the long beam and the rafter in a roof body structure is low, can thus be improved, and a lightweight roof body structure having a sufficient pressure withstanding property can be provided.

摘要： PURPOSE:To improve workability for mounting an inside panel by providing a packing, consisting of an elastic material and a surface protecting member, in a joint of the fellow inside panels, placing an end part of each inside panel on this packing, and fixing the inside panel to a vehicle body frame by fasteners provided in both sides of the packing. CONSTITUTION:In a joint part of inside panels 11, 12 in an end of a body 10 of a rolling stock, a material, in which an elastic unit 14 consisting of sponge or the like is previously adhesively attached to a surface protecting rubber 15, is adhesively attached to a body frame 13, and two-sheet one set of fasteners 16, 17, having mutually meshing protrusions 18 in the both sides, are mounted to each body frame 13 and reverse sides of the inside panels 11, 12 to mount the inside panels 11, 12 by pressing them to a side of the body frame to mesh the protrusions 18... with each other. In this way, a double level, even when it is provided between surfaces of the inside panels 11, 12, can be absorbed by the elastic unit 14, and appearance is prevented from deteriorating by generating no space between the surface protecting rubber 15 and the inside panels 11, 12.

摘要： PURPOSE:To reduce fitting manhour of inner facing material by using a body inner skeleton formed into one body out of thin plates. CONSTITUTION:A door pocket tart inner skeleton 2 and a curtain part inner skeleton 3 are respectively formed in one body out of solid plates provided with reinforcing ribs 9 by burring work for example. They are fitted to an inside panel support 5 provided on a side post 4 of a body 1 by a joining means 6 such as rivet. The overlapped part of both inner skeletons 2,3 is provided with a necking part 7 of the plate tickness of the curtain part inner skeleton 3, and fitted to the flange of the inside panel support 5. Hereby, generation of a step-difference part is eliminated, continuous plane finishing can be obtained, and fitting of inner facing material is simplified.
