Abstract

PURPOSE:To improve the reliability of sealingness and reduce the manufacturing cost of the joint by inserting a pipe joint having shoulder into a cylindrical hole and compressing a pipe-formed ring member interposed between the cylindrical hole and the pipe joint by the shoulder and the outer cylindrical surface of a cylinder. CONSTITUTION:The pipe joint 13 having the shoulder 12 is inserted at the tip end 11 into the cylindrical hole 6 with the pipe-formed ring member 14 interposed therebetween, the ring member 14 compressed by the shoulder 12 and the outer surface 16 of the cylinder 2. This enables a sealing of the joint at two pressure insertion points which are formed in continuation without welding parts. Thus, the reliability of the sealingness of the joint. Further, since the number of parts required is much reduced, the manufacturing cost can also be much reduced.
