PROBLEM TO BE SOLVED: To provide a vibration-proof device that can be manufactured by a simple method where a spring rate in a direction different from an inputting direction of main vibration is sufficiently controlled.SOLUTION: This invention relates to a vibration-proof device 1 comprising an outer fixing member 2 connected to any one of a vibration generating part and a vibration receiving part, an inner fixing member 3 connected to the other, and a resilient body 4 connecting these members 2, 3. The outer fixing member 2 is formed into a cylindrical shape, the inner fixing member 3 comprises a rigid member 31 arranged in the outer fixing member 2 and an inner installed member 32 positioned in the outer fixing member 2 and made of synthetic resin material fixed to the rigid member 31. The inner installed member 32 is formed with a first protrusion part 32a protruded toward outside in a radial direction. The outer fixing member 2 is formed with a second protruding part 24a protruded toward inside in a radial direction. The first protrusion part 32a and the second protrusion part 24a are coincided to each other at their circumferential directions and their axial positions are made different to each other.SELECTED DRAWING: Figure 1 |
