PROBLEM TO BE SOLVED: To provide a vibration control device, suitably lowering a dynamic spring constant in the vertical direction without impairing durability. SOLUTION: In this vibration control device, inner and outer cylindrical metal fittings 1, 2 are coupled by a rubber elastic body 3, and the rubber elastic body 3 has cavity parts 4, 5 on the upper and lower sides of the inner cylindrical metal fitting. The lower cavity part 5 is provided with a projecting part 6 projected upward to allow a ceiling surface 51 of the cavity part 5 to abut thereto under the load. A small cavity 61 formed of an axial through hole is provided in the projecting part 6. COPYRIGHT: (C)2005,JPO&NCIPI |
