<p><P>PROBLEM TO BE SOLVED: To solve a difficulty in installing a circulator to the ceiling, on which a lighting facility has already been installed, due to the need of a wide hollowed- out part in the ceiling for suspending members installed on the outer side surfaces of the body because the circulator is a heavy object and must be formed as a structure to be suspended from above even when embedded in the ceiling. <P>SOLUTION: The body is reduced in space by fixing the body and the suspending member inside the body, so that it is housed in the existing hollowed- out part arranged for the lighting facility. <P>COPYRIGHT: (C)2003,JPO</p> |
