Zusammenfassung:To provide a hermetically sealed structure which has low friction and exerts stable seal performance.SOLUTION: A groove side surface (30) of a low pressure side (L) of a seal concave groove (3) is like a slope inclined toward the inside of the groove. A resin ring (4) mounted inside there has a low pressure side gradient surface (8) coming into abutting contact with the slope-like groove side surface (30) of the seal concave groove (3), and furthermore reduces friction resistance by the elastic ring (5).SELECTED DRAWING: Figure 2 【課題】低摩擦であり、安定したシール性能も発揮する密封構造体を提供する。【解決手段】シール凹溝（３）の低圧側（Ｌ）の溝側面（30）が、溝内方向へ傾いた傾斜状であり、これに内装される樹脂リング（４）は、シール凹溝（３）の傾斜状の溝側面（30）に当接する低圧側勾配面（８）を、有し、さらに、弾性リング（５）によって、摩擦抵抗を減少させる。【選択図】図２
