To restrain deterioration of strength.SOLUTION: A joint structure includes: a first member 110 having a fitting groove 116; a second member 120 having an insertion portion 124 inserted into the fitting groove 116, and made of a material different from the first member 110; and a plurality of adhesion layers 130, 132 formed between the fitting groove 116 and the insertion portion 124, and having different hardness. In adhesion between the members made of different kinds of materials, it is possible to restrain deterioration of strength which is caused by occurrence of cracks in the adhesion layers due to difference of a deformation amount owing to the difference in rigidity between the first member 110 and the second member 120.SELECTED DRAWING: Figure 4

    【課題】強度の低下を抑制する。【解決手段】継手構造は、嵌入溝116を有する第1部材110と、嵌入溝116に挿通される挿通部124を有し、第1部材110と異なる素材からなる第2部材120と、嵌入溝116と挿通部124との間に形成され、硬度を異にする複数の接着層130、132と、を備える。異種材料からなる部材間の接着において、第1部材110、第2部材120の剛性の違いによる変形量の差から接着層にき裂が生じることによる強度低下が抑えられる。【選択図】図4
