PURPOSE: To facilitate a work for swingably and rotatable hanging a rotary pipe with respect to a ceiling fitting by forming a spherical head at the top end via a reduced neck and by arranging a rotary pipe to be threadably connected with a hanging pipe at the lower portion.
CONSTITUTION: A spherical head 2 with its lower surface being a semi-spherical one is formed at the top end via a reduced neck portion 1, a rotary pipe 4 having internal threaded grooves at the inner circumferential surface with which the upper outer threaded end of the hanger pipe 3 is threadably engaged has a cup-shaped curve surface 7 at its inner circumferential surface, and the rotary pipe is guided from the outside of the rotary seat 5 to the inside at the neck portion 1 via recessed grooves with their circumferential part of the rotary seat 5 having a fixing recess 23 at the top outer circumference and a threaded part 5a to be engaged with a step ring 17 at the lower outer circumference. The rotary pipe 4 is swingably and rotatably hang against the rotary seat 5 by abutting and engaging the lower surface of the sperical head 2 with the cup-shaped curved surface 7 of the rotary seat 5.
