PROBLEM TO BE SOLVED: To provide a rubber laminated type mount of a vibration-proof device for housing in which a natural frequency can be set to a comparatively high natural value while enabling suppression of creep variation and the tuning width of the natural value can be enlarged. SOLUTION: The rubber laminated type mount of the vibration-proof device for housing comprises a first mounting member 1, a second mounting member 2, 7 sheets of intermediate bearing plates 3 laminated and arranged at a distance between the first and the second mounting members 1, 2, and a rubber laminated body 4 consisting of 8 pairs of rubber elastic bodies 41 arranged between the first and the second mounting members 1, 2 and between the two adjacent tilting sections of the intermediate bearing plates 3. The tilting angle of the tilting sections of the first and the second mounting members 1, 2 and the intermediate bearing plates 3 is set to a range of 15°to 45°. The width in the Y direction of the rubber elastic bodies 41 is set to 45 mm or more. The thickness between each tilting section is set to a range of 5 to 7 mm. The natural frequency as an auxiliary vibration system is tuned to a range of 5 to 10 Hz. COPYRIGHT: (C)2008,JPO&INPIT
