PURPOSE:To continuously use a bearing without abnormal wear or seizure for a long period by providing many recesses at least on one surface of a base plate opposed to an oil storage plate. CONSTITUTION:An ultrafine pattern which has many recesses 141 is formed on the entrire surface of a base plate opposed to an oil storage plate 14. Since the contacting area of the plate 14 with the oil increases by the recesses 141, the power of the oil to be bonded to the plate 14 is improved. |
