PURPOSE:To easily mount a ceiling ventilating fan in the ceiling by providing on a pendant fitment a temporary stopper plate where a width size has a specific notch. CONSTITUTION:Upon mounting a body on an anchor bolt, the anchor bolt is inserted into a front half of a through-hole 19a where a temporary plate 22 is not present and simultaneously a pendant fitment 19 is passed over through the anchor bolt. Thereafter, the suspension fitment 19 (body) is directed to slide in the direction where it goes along the through-hole 19a (forward direction in the figure. Hereby, a notch 22a in the temporary plate 22 is inserted into the anchor bolt to the middle of the same. Since the width size of the notch 22a is smaller than the outer diameter but is larger the root diameter, the temporary stopper part 22a is caught by the thread of the anchor bolt for manifestation of temporary stopping, whereby ther suspension fitment 19, particularly the body are held in a temporarily stopped state. |
