At least one of the shaft body 6 and the bearing body 8 is provided with a dynamic pressure generation groove 50 for generating a dynamic pressure to a lubricant 20. The bearing body 8 is provided with an axially penetrating communication passage BP for the lubricant 20 on a position deviated from the rotating shaft R. The communication passage BP has an opening at one side formed on one end face of the bearing body 8, and an opening at the other side formed on the other end face of the bearing body 8. The communication passage BP includes an inner part 44a in which capillary force is gradually reduced from one opening toward the other opening, on an inner region close to the rotating shaft R.SELECTED DRAWING: Figure 2
