<P>PROBLEM TO BE SOLVED: To improve work efficiency in assembling a nut while being compact and cutting down the number of components and to secure strength in a ceiling suspended type vibration control device. <P>SOLUTION: The ceiling suspended type vibration control device 1 includes a housing 2 integrally formed, by bending a metal plate, with an upper plate 3 and a lower plate 5 respectively formed with through holes 5c, 5d for inserting through a hanging bolt connected to the ceiling and equipment respectively, and a pair of side plates 7, 9 connecting these plates 3, 5. The hanging bolt is mounted to the lower plate 5 by a nut, while the hanging bolt is mounted to the upper plate by a nut through a coil spring 33. The pair of side plates 7, 9 are formed with notches 7a, 9a in the portions lower than the tip of the coil spring 33 in the non-suspended state of a supported body. The lower plate 5 is formed by superimposing extended parts 5b, 5a of the side plates 7, 9 bent at a substantially right angle. <P>COPYRIGHT: (C)2011,JPO&INPIT |
