PROBLEM TO BE SOLVED: To provide a vibration control device, in which a strain is difficult to accumulate, yield and exchange works are easy to conduct. SOLUTION: A space-structure ceiling body 16 is roller-supported 20 by main supports 17 at four corners, and energy absorption devices 1 are installed at the sites of vibration-control supports 18 at four places among the main supports 17 and beams 19 in the upper sections of the vibration control supports 18. Energy absorbers 12 are disposed upright in the upper sections of the vibration- control supporters 18, and the mutually opposite sites of spherical head sections 10 are inserted or set into groove sections 4 formed by the holding members 5 and 5 of the bottom sections of the beams 19 so as to be brought into contact with interior walls (hard plates 2 and 2) or be inserted or set in an extent that openings can be formed slightly.
