To provide a junction structure capable of facilitating joining and having great strength and accuracy in such a case that thick parts of a railway vehicle structure are joined by combining the different or same type of carbon fibers, glass fibers or metals, in order to solve a problem of not being capable of adapting a junction structure for easily combining an indention and a projection in joining.SOLUTION: A junction structure, in which a projection and an indention are made opposed to each other and the different or same type of carbon fibers, glass fibers or metals are combined using a fastening member, is characterized in that: the projection is formed in a shape shrinking toward the upper direction; an indention shrinks toward the lower direction so as to be tightly adhered with the projection; a shape in the vicinity of the lowermost part is formed in a shape having a gap between itself and the vicinity of the uppermost part when joined with the projection; and a position going through the uppermost part and the lowermost part of the joined projection and indention is arbitrarily selected and fixed with the fastening member.SELECTED DRAWING: Figure 1

    【課題】接合においては、容易に凹凸を組み合わせる接合構造を採用することができない問題があった。鉄道車両構体の厚み部分をカーボン繊維、ガラス繊維又は金属の各々を異種又は同種に組み合わせて接合するような場合において、容易に接合ができ、かつ、高い強度と精度を有する接合構造を提供することを目的とする。【解決手段】本発明の接合構造は、凸部と凹部を相対させて締結部材を用いてカーボン繊維、ガラス繊維又は金属の各々を異種又は同種に組み合わせる接合構造において、凸部が、頂上方向に向かって縮小する形状に形成され、凹部が、前記凸部と密着可能に底方向に向かって縮小し、最底近傍の形状が前記凸部と接合させた際に最頂上近傍との間に隙間を生じさせる形状に形成されて、接合させた凸部と凹部の最頂上と最底とを貫く位置を任意に選択し締結部材を用いて固定すること、を特徴とする。【選択図】 図1
