To reduce slide resistance of a slide portion of an O ring to reduce twisting of the O ring in a rotation direction during sliding action of the O ring, inhibit or prevent twisting of the O ring in a circumferential direction, and thereby improve sealing action of the O ring.SOLUTION: An O ring arrangement structure in a slide fitting part is formed having: one slide member (a holder) 30; the other slide member (a sleeve) 34; a recessed shape 38; and an O ring 36 which is loaded into the recessed shape 38 in a compressed state and functions as a sealing between the one slide member (the holder) 30 and the other slide member (the sleeve) 34. A coating agent 46 for achieving reduction of slide resistance is applied to a range of a slide contact surface in the O ring 36 loaded into the recessed shape 38.SELECTED DRAWING: Figure 6 【課題】Ｏリングの摺動部位個所の摺動抵抗を低減させることにより、Ｏリングの摺動作用時におけるＯリングの回転方向の捩じれの減少を図って、Ｏリングの円周方向の捩じれの抑制ないし防止を図り、Ｏリングのシール作用の向上を図る。【解決手段】摺動嵌合部におけるＯリング配設構造は、一方の摺動部材（ホルダー）３０と、他方の摺動部材（スリーブ）３４と、凹部形状３８と、凹部形状３８内に圧縮状態で装填されて、一方の摺動部材（ホルダー）３０と他方の摺動部材（スリーブ）３４間のシール作用を行うＯリング３６とを有して構成される。そして、凹部形状３８内に装填されたＯリング３６における摺動接触面の範囲を摺動抵抗の減少を図るコーティング剤４６で塗布されてなる構成である。【選択図】図６
