PROBLEM TO BE SOLVED: To provide a vibration-proof support device capable of restricting change of low dynamic spring properties at the time of a low input load and dynamic spring properties to load change at the time of a high input load, and having effect on vibration properties in such a range as to increase static spring properties. SOLUTION: In an inner cavity 30 in main body rubber 16 of a hollow conical form, an inner stopper 18 of a hollow conical form is disposed, and an inner cavity in the inner stopper 18 is set as a sealed gas-tight air chamber 40. It bears an input load at the time of compression shearing deformation, and it achieves effect as an air spring. Static spring properties of the rubber itself can thus be designed small. The dynamic spring properties can be restricted low. COPYRIGHT: (C)2005,JPO&NCIPI |
