Abstract:
A carbon brush that suppresses a wear amount of a carbon commutator and has less swelling is provided. The carbon brush has a part connected to a lead and is one that slides in contact with a carbon commutator that is used in a fuel pump. The bulk density of the carbon brush is 1.85 g/cm3 or less, and the shore hardness of the carbon brush is 40 or less.
