PROBLEM TO BE SOLVED: To suppress cumulative plastic deformation of hanging bolts while increasing the degree of freedom of installation by dispensing with a brace between the hanging bolts, in a vibrational energy-absorbing suspension structure reducing vibrations of suspension equipment suspended from a ceiling slab by the hanging bolts.SOLUTION: A connector 15, in which upper and lower brackets 16 and 17 are combined together, is provided at a ceiling slab-side base end of a hanging bolt. A steel ball 18, which is sandwiched between locking surfaces 16a and 17a of the upper and lower brackets 16 and 17 to bear a load of suspension equipment and which makes the upper and lower brackets 16 and 17 relatively displaceable in a horizontal direction, is interposed between the upper and lower brackets 16 and 17 of the connector 15. |
