Zusammenfassung:PURPOSE:To prevent loosening and release of connection made by jointing in a screwed-in state between a part on the indoor side and a part on the outdoor side. CONSTITUTION:A locking piece 9 is cut and raised on the connection end side of an outer cylinder 2 of a part 4 on the outdoor side, being the internal engaging side, through connection made by jointing in a screwed-in manner and in an outer periphery within the range of the jointing in a screwed-in state. An engaging hole 10 through which the locking piece 9 is engaged in a given screwing-in depth with an outer cylinder 2 on the internal engaging side is formed on the connection end side of the outer cylinder 2 of a part 3 on the indoor side being the external engaging side. This constitution fixes a jointing state in a screwing-in manner between the outer cylinders on a part on the indoor side and a part on the outdoor side and a screwing-in depth through engagement between the engaging piece and the engaging hole, and prevents loosening and release of a jointing state in a screwing-in manner.
