PROBLEM TO BE SOLVED: To provide an extruded shape member of a flame-resistant magnesium alloy, a body structure of a railway vehicle, and a body structure of a traffic transportation means capable of reducing weights thereof by using the flame-resistant magnesium alloy.SOLUTION: An outside plate 3 is a part constituting a plate on a vehicle outer side of a body structure 2. The outside plate 3 is an extruded shape member made of a flame-resistant magnesium alloy including calcium. The outside plate 3 is formed in a shape having a rib by an extrusion method, and also formed as a T rib shape member having a T-shaped cross section. A plate-like part 3a is a part constituting a body part of the outer plate 3. A rib part 3b is a part providing rigidity to the plate-like part 3a, and protrudes from one of surfaces of the plate-like part 3a, and is integrally formed with the plate-like part 3a. The rib part 3b is formed on a surface of the plate-like part 3a on an inner side surface side of the outer plate 3. The flame-resistant magnesium alloy may be preferably, for example, a Mg-Al-Zn-Ca alloy or a Mg-Al-Mn-Ca alloy.SELECTED DRAWING: Figure 2

    【課題】難燃性マグネシウム合金を用いることによって重量を軽減することができる難燃性マグネシウム合金の押出形材、鉄道車両の構体及び交通輸送手段の構体を提供する。【解決手段】外板3は、構体2の車外側の板を構成する部分である。外板3は、カルシウムを含有する難燃性マグネシウム合金の押出形材である。外板3は、押出法によってリブ付形材に成形されており、断面形状がT字状のTリブ形材に成形されている。板状部3aは、外板3の本体を構成する部分である。リブ部3bは、板状部3aに剛性を付与する部分であり、板状部3aの一方の表面から突出してこの板状部3aと一体に形成されている。リブ部3bは、外板3の内側表面となる側の板状部3aの表面に形成されている。難燃性マグネシウム合金は、例えば、Mg-Al-Zn-Ca合金又はMg-Al-Mn-Ca合金が好ましい。【選択図】図2
