SEAL STRUCTURE
Document Type and Number:
Japanese Patent JP2021196040
Kind Code:
A
Abstract:
To improve a sealing property on a connection surface of two connection members.SOLUTION: Two connection members (10A, 10B) are connected to each other to form a flow channel (P1, P2). A metal seal (20) is formed in a ring shape, and arranged along an inner peripheral surface of the flow channel. A recessed part (30) is formed by two connecting surfaces (11), and stores the metal seal in a state of opening toward an inner side of the flow channel. A pair of flat regions (14) extend in a direction perpendicular to a longitudinal direction of the flow channel from an opening end of the recessed part, and sandwiches the metal seal in a longitudinal direction of the flow channel. A pair of hook parts (13) project in a direction closer to each other from each of the pair of flat regions. The metal seal deforms according to an engagement of the hook part, and closely contacts the pair of flat regions.SELECTED DRAWING: Figure 1
