BEARING DEVICE

PROBLEM TO BE SOLVED: To prevent the dust entering a rubber-like elastic body part discharging an important part for bearing while following the movement when an upper structure is deflected to show bearing operation in a stable state over a long period of time and, at the same time, to simplify a structure by eliminating a dust-proof device. SOLUTION: A bearing device is constituted of an upper bearing member 1, a lower bearing member 2 a rubber-like elastic body 3 mounted between both bearing members 1 and 2. In that case, the lower surface of the upper bearing member 1 makes it as a projected or a recessed spherical curved face 11, at the same time, the upper surface of the lower bearing member 2 makes it as a recessed or a projected spherical curved face 21, the rubber-like elastic body 3 mounted to both curved faces 11 and 21 is stratified and, at the same time, both upper and lower surfaces of the rubber-like elastic body 3 are respectively fixed to both curved faces 11 and 21.
