ある。However, in the latter flexible joint 1 for branch pipe connection, the rigid member 5 is embedded inside the saddle portion 3 along the shape of the saddle portion 3 having an arc-shaped cross section. The shape of the rigid member 5 is the same as that of the saddle portion 3, and therefore, when the saddle portion 3 and the rigid member 5 are simultaneously molded, the position A of the uppermost surface of the rigid member 5 buried by the thermal softening phenomenon. In other words, there is a problem in that deformation occurs at the apex of the circular cross section, resulting in quality deterioration. In addition, since the saddle portion 3 is not flexible due to the embedding of the rigid member 5, the degree of freedom such that the lower end portions 3a of the saddle portion 3 slightly expand in the left-right direction X so as to open the opening cannot be obtained. For this reason, when installing the branch pipe connecting flexible joint 1 in the main pipe M, it is necessary to set the center of the main pipe M so as to be aligned with the center of the saddle portion 3, so that the operation is complicated.

To the extent that it can be spread slightly. Therefore, when the branch pipe connection flexible joint 1 is installed on the main pipe M, it is not necessary to make the center of the main pipe M completely coincide with the center of the saddle section 3, and the center of the saddle section 3 is slightly shifted left and right. Even if it is misaligned, it is automatically corrected to be at the center by the flexibility of both lower end portions 3a of the saddle portion 3.

The joint body 2 is set on the main pipe M. At this time, an unvulcanized butyl adhesive is provided on the contact surface between the saddle portion 3 and the main pipe M to form a water-stopping material. Next, the saddle part 3 is crimped to the main pipe M by the joint body fixing band 6. Then, the branch pipe B is inserted into the cylindrical part 4 until the tip of the branch pipe B comes into contact with a stopper 9 provided on the inner wall of the cylindrical part 4, and the branch pipe B is inserted into the cylindrical part 4 by the branch pipe fixing band 7.
