PROBLEM TO BE SOLVED: To ensure sealing performance and stabilize characteristics even when using a partition member of an all-elastic body. SOLUTION: A vibration control device 1 is provided with a tubular first attachment member 6, a second attachment member 7, a rubber elastic body 8, a diaphragm 5, and a partition member 4. The partition member 4 consists as a whole of an elastic body. The first attachment member 6 is provided with a projection portion 60 and a first tubular portion 62. An annular hard member 50 is mounted on the inner side of the first tubular portion 62, and the hard member 50 is provided with a second tubular portion 53 and a supporting portion 54. Further, either of the first and second tubular portions 62 and 53 is mounted on the inner side of the other. The member 6 having the other tubular portion 62 includes a locking portion 60 with which one end of the one tubular member 53 is locked and a caulking portion 64 bent radially inward to lock the other end of the one tubular portion 53. The one tubular portion 53 is sandwiched between the locking portion 60 and the caulking portion 64, and the partition member 4 is sandwiched between the projection portion 60 and the supporting portion 54.
