Abstract
A fuel injection pump includes a cam shaft ( ) driving a plunger ( ) and a feed pump ( ) assembled therein for feeding fuel pressured by the plunger ( ). A flange part ( ) projecting radially is provided on the cam shaft ( ), an internal gear ( ) transmits a power to the feed pump ( ), and a housing member ( ) rotatably supports the cam shaft ( ) on the free end opposite to the end part of the driven side of the cam shaft ( ). A housing member ( ) rotatably supporting the cam shaft ( ) through a radial bearing ( ) is held between the flange part ( ) and the internal gear ( ) so as to allow adjustment of the axial position of the cam shaft ( ), so that adjustment of the axial position of the cam shaft is substituted for the existing member assembled into the pump. Thus, an axial gap due to a deterioration of durability of the bearing is eliminated to be adjusted so as to facilitate the assembly, reduce the number of parts, and reduce the size of the injection pump.
