摘要： A highly reliable combined bearing (10) capable of achieving equal and sufficient lubrication of a plurality of rolling bearings with a simple and compact structure is provided. The combined bearing includes a first rolling bearing (11) and a second rolling bearing (13) which are in contact with each other and arranged on the same axis; and a lubricating-oil inlet (15) for introducing a lubricating oil into an inner space formed between the first rolling bearing and the second rolling bearing, the lubricating-oil inlet (15) being provided on at least one of an outer ring (11b) of the first rolling bearing (11) and an outer ring (13b) of the second rolling bearing (13).
