PROBLEM TO BE SOLVED: To provide a vibration-control mount which secures both of excellent vibration-control performance by a mount main body and durability of the mount main body relative to the weight of a supported body and an input of static displacement due to prying displacement. SOLUTION: This vibration-control mount includes a first and a second fitting plates 11 and 12 arranged opposite to each other, a mount main body 13 integrally provided between the first and the second fitting plates and formed from a rubber-like elastic material, and an annular elastic body 14 fitted on the periphery of the mount main body 13 and arranged between the first and the second fitting plates 11 and 12 without adhesion to them in the state of being possible to be brought in contact with the first and the second fitting plates 11 and 12. When a prying displacement is input, since the annular elastic body 14 is compressed between both the fitting plates 11 and 12 at the point in time when the mount main body 13 is compressed in a certain degree on a side wherein both the fitting plates 11 and 12 approach each other, rigidity against the prying displacement rises, and a shearing spring in the twisting direction is practically carried by the only mount main body 13, and excellent insulation performance against the twisting vibration is thereby secured.
