の使い勝手が向上する。In the header according to the first aspect, the first locking portion of the insertion portion and the second locking portion of the receiving portion of the adjacent joint are fastened by the connecting and fixing member, so that the joint rotates. Since the branch is kept in a fixed direction without the risk of fluid leakage or disconnection of the joints even during long-term use, reliability is improved and the fastening by the connection fixing member is slightly loosened. Thereby, the joint rotates without leaking the fluid, the fine adjustment of the piping after the construction is facilitated, and the branch part can be directed in a desired direction, so that the usability at the time of the construction and the like is improved.
