ABSTRACT:
A joint for bringing into communication a first fluid passageway and a second fluid passageway of a nut member includes a push rod and a main body. The main body forms a push rod storage space, a communication path, a seal structure forming part and a male thread part. The push rod storage space houses the push rod so that one part of the push rod protrudes along a push rod longitudinal direction. The seal structure forming part is capable of forming a seal structure by contacting a first tapered part of the nut member. The male thread part is capable of screwing together with a female thread part of the nut member such that the seal structure forming part contacts the first tapered part. The part of the portion of the push rod contacts one part of the nut member.
