Abstract
A high pressure fuel pump () that pressurizes and supplies a fuel by driving a cam () such that a plunger () reciprocates, the high pressure fuel pump () comprises a lifter guide () having a guide hole (A), a lifter () that is disposed between the cam () and the plunger () and is fitted into the guide hole (A) to be free to slide so as to transmit a driving force from the cam () to the plunger (), an oil collection portion () that is provided above the guide hole (A) so as to surround a periphery of the lifter (), and stores a lubricating oil for lubricating a sliding portion between the lifter () and the guide hole (A), and an oil supply passage (C) for supplying the lubricating oil to the oil collection portion (). As a result, a reduction in a lubricating performance with regard to the lifter () in a position away from an opening portion of the oil supply passage (C) is suppressed.
