Abstract
A bearing has a composite elastic member, which supports a shaft. The composite elastic member comprises an elastic cylinder, which is made of an elastic material such as rubber and is provided at a bearing body section; and a spiral member, which projects from the circumferential surface of the elastic cylinder and is spirally assembled on the elastic cylinder. A lubricant is supplied to a spiral gap, which is divisionally formed between threads of the wire material forming the spiral member. When the shaft rotates, leakage of the lubricant is prevented by pumping operation and leakage of a fluid is prevented.
