PROBLEM TO BE SOLVED: To provide a vibration isolating support mechanism of a double floor by dividing a support to support a floor panel up and down on a floor slab, connecting the divided support by interposing a cushioning member and absorbing vibration caused by walking without lowering an earthquake-proofing strength. SOLUTION: A foundation support part 2 to be set on a floor slab G and a floor panel support part 3 to support a grating 50 which is a kind of floor panel are connected to each other through a cushioning part 4. The cushioning part 4 is constituted of rubber, lead, viscous fluid such as silicone and a cushioning material such as a spring and it is made to absorb vibration propagated to the grating 50. Additionally, in the case of supporting a fulcrum (corner) of the grating 50, a divided support member is interposed on an upper base set 7 and the corner of each of the gratings is separately supported so that vibration of the one grating does not propagate to the other grating. Furthermore, it is devised so as not to cause lowering of fixing strength of the floor panel 50 to the floor slab G. Consequently, it is possible to provide a floor panel support mechanism doubly furnished with a vibration isolating property and an earthquake-resistant property.
