To provide a seal structure that has high sealability and can be applied to a large case by using an elastomeric seal member.SOLUTION: A sealing structure includes a first member 2, a second member 3, and an elastomeric sealing member 4 compressed between the first member 2 and the second member 3. A groove 22 for accommodating the seal member 4 is formed at the seal interface of at least one of the first member 2 and the second member 3. The seal member 4 includes an overlapping portion 40 in which a plurality of end portions 41 and 42 overlap in the width direction of the groove 22. In the pre-compression state before the seal member 4 is disposed in the groove 22 and compressed, the cross-sectional area of the overlapping portion 40 is larger than the cross-sectional area of the groove 22 in which the overlapping portion 40 is disposed.SELECTED DRAWING: Figure 1 【課題】 エラストマー製のシール部材を用いて、シール性が高く、大型のケースにも適用することができるシール構造を提供する。【解決手段】 シール構造は、第一部材２と、第二部材３と、第一部材２と第二部材３との間で圧縮されるエラストマー製のシール部材４と、を備える。第一部材２および第二部材３の少なくとも一方のシール界面には、シール部材４を収容する溝部２２が形成されており、シール部材４は、溝部２２の幅方向に複数の端部４１、４２が重なる重複部４０を有する。シール部材４が溝部２２に配置され圧縮される前の圧縮前状態において、重複部４０の横断面積は、重複部４０が配置される溝部２２の横断面積よりも大きい。【選択図】 図１
