<p>A fuel injection pump, comprising a cam shaft (7) driving a plunger (4) and a feed pump (3) assembled therein for feeding fuel pressured by the plunger (4), wherein a flange part (52) projecting radially is provided on the cam shaft (7), an internal gear (41) transmitting a power to the feed pump (7), and a housing member (8c) rotatably supporting the cam shaft (7) on the side opposite to the end part of the driven side of the cam shaft (7), and a housing member (8c) rotatably supporting the cam shaft (7) through a radial bearing (12) is held between the flange part (52) and the internal gear (41) so as to adjust the axial position of the cam shaft (7), and then a function to adjust the axial position of the cam shaft is substituted for the existing member assembled into the pump, whereby 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. <IMAGE></p> |
