ABSTRACT:
A bearing for a fuel pump includes a sliding layer made of mainly carbon, and a supporting layer made of mainly carbon and a metal. The supporting layer is connected to the sliding layer to support the sliding layer. Because the sliding layer of the bearing is made of mainly carbon, corrosion resistance of the bearing can be improved. Further, the supporting layer improves the strength of the bearing. Accordingly, the bearing with the two-layer structure effectively improves the corrosion resistance while the strength thereof can be increased. The bearing can be suitably used for the fuel pump. In this case, the bearing is press-fitted to a casing member on the supporting layer, and a rotary shaft of the fuel pump is slidably held in the bearing on the sliding layer.
