PROBLEM TO BE SOLVED: To improve reliability and durability of an oil-impregnated sintered bearing used for combining rotating members to a fixed shaft without introducing specified manufacturing method, and to make easy replacement. SOLUTION: In this device, a sintered bearing 14 possible to provide baffle to fixed shafts 15, 25 by a baffle means 17 is attached, and the sintered bearing 14 is inserted in an insert hole 13 of a rotating member 12. The baffle means 17 is formed on a flange 18 side to be provided at one end along the axial direction of the sintered bearing 14 as a baffle hole 19. It is also formed on the surface of fixed walls 16, 26 as a baffle pin 20 to be inserted in the baffle hole 19. The sintered bearing 14 is used under non-rotating conditions. Hence, the impregnated lubricating oil can not be lost by a centrifugal force, and lubricating oil can be applied to a sliding surface between the rotating member 12 and the insert hole 13 for a long period. |
