PROBLEM TO BE SOLVED: To provide a joint for high pressure capable of improving sealability and vibration resistance of joints.SOLUTION: The joint for high pressure comprises: a first joint; a second joint; a pair of clamp members including band parts for covering abutting portions of the joints; a seal member; and a fastening member that reduces an inner diameter of the band part. An outer diameter at each end of each of the joints in the abutting portion is larger than an outer diameter of an intermediate part of each of the joints, and an inner surface of the band part is formed in such a manner that the inner surface of the band part in the clamp member is fitted with the end of each of the joint while abutting the first joint and the second joint. The clamp members are formed from a first clamp 4a including a first through-hole 8a that becomes an insertion port of the fastening member, and a second clamp 4b including a second through-hole 8b that becomes a release port of the fastening members (5a and 5b). The first clamp 4a and the second clamp 4b are designed in such a manner that, when the ends of the joints and the inner surfaces of the band parts are abutted and fitted, a gap 10 is generated without abutting inner surfaces of the fastening parts.SELECTED DRAWING: Figure 3 |
