摘要： An annular recess portion (7) is provided in an end face of a synthetic resin-made first joint member (2) and an annular projection portion (8) is provided on an end face of a synthetic resin-made second joint member (3). The projection portion (8) is fitted into an opening portion of the recess portion (7) into which a synthetic resin-made gasket (4) is fitted. When a pipe joint(1) is tightened adequately, the inner face of the recess portion (7) of the first joint member (2) and the outer face of the projection portion (8) of the second joint member (3) are in close contact with each other over substantially the entire surface through the gasket (4), a portion (2d) located radially inside the recess portion in the end face of the first joint member (2) and a portion (3d) located radially inside the projection portion on the end face of the second joint member (3) are in close contact with each other over substantially the entire surface area, and a portion (2e) located radially outside the recess portion in the end face of the first joint member (2) and a portion (3e) located radially outside the projection portion on the end face of the second joint member (3) are also in contact with each other over substantially the entire surface area.
