PROBLEM TO BE SOLVED: To provide a bearing device capable of circulating and feeding lubricant for an oil reservoir without enlarging the device or complicating its structure. SOLUTION: The bearing device 1 comprises a pump to be driven by a plunger 10 adapted to pump the lubricant inside a first unit 1A or a second unit 1B. The pump is connected with the oil reservoir 8 for forming a passage 20 so as to circulate and feed the lubricant for the oil reservoir 8 to drive the pump on the basis of relative rotation of the first unit 1A with the second unit 1B for circulating the lubricant by force.
