摘要： PROBLEM TO BE SOLVED: To control the lubricated condition of the friction surfaces in between of two frictional members. SOLUTION: An insulating material layer 15 and a sliding material layer are laminated on a movable electrode 14, while an insulating material layer 13 and a porous sinter layer 11 to slide with the sliding material layer 16 are laminated on a stationary electrode 12. The porous sinter layer 11 has open pores 11c leading from the sliding surface 11a to the other surface, and the pores 11c contain lubricating oil which can form electric double layer at the interface with the porous sinter layer 11. When an electric field is impressed between the stationary electrode 12 and movable electrode 14 positioned opposing, the lubricating oil in the pores 11c makes movement owing to the electroendosmosis in the direction decided by the ζ-potential (potential difference between inside the oil and the sliding surface).
