Sliding member
In order to improve conformability of a sliding surface of a sliding member in an early state of sliding, there is provided a sliding member in which a plurality of holes are formed on a sliding surface, and the diameters (or the opening area) of the holes on the sliding surface are arranged so as to become gradually large as it gets closer to both ends in an axial direction from the center side in the axial direction. This feature decreases the pressurized area as it gets closer to the ends of the sliding surface so that it wears at an early stage, whereby a conformed surface following the deflection of a mating member is provided.
