PURPOSE:To provide a smooth bearing structure whose rotation is not disturbed when taking measurements of minor vibrations in a rotary body under rotation, and also provide a vibration detecting device which can detect minor vibrations of the rotary body, in the bearing structure to support the rotary shaft of a motor or the like. CONSTITUTION:An annular clearance is formed between an external surface of the shaft 2 of a rotary body 1 and the inner surface of a bearing 3 to support the shaft, and there is provided a fluid supplying means 42 to supply fluid into this annular clearance, leading to formation of a fluid layer in the clearance. A constitution is made so as to support the shaft 2 by this fluid layer. |
