An improved wear resisting structure of a fuel injection pump is provided. The fuel injection pump has a plunger reciprocating to pressurize fuel within a compression chamber and a cam mechanism installed on a torque input shaft. The cam mechanism revolves following rotation of a torque input shaft to move the plunger. Washers are installed fixedly within washer chambers formed in an inner wall of the housing. The washers work as bearing surfaces which are in contact with and holds the cam mechanism from moving in an axial direction thereof, thereby avoiding excessive wear of portions of the housing.
