Abstract
In a fuel injection pump, a helical gear is attached to an end of a camshaft and rotatable with the camshaft. The camshaft is biased in one axial direction thereof by a driving force that the helical gear receives from an engine crankshaft. A disk is provided in a position of the camshaft extending forward from a cam to the direction in which the camshaft is biased. An axial movement of the disk is restricted via a washer by an end of a bearing cover. The disk is formed in the same axis to a portion of the camshaft that is held by a journal bearing. An outer diameter of the disk is larger than that of the cam. An area where the disk and the washer are in sliding contact with each other is relatively large and the sliding regions thereof are constant so that hammer noises are prevented and frictional wear thereof are limited.
