PROBLEM TO BE SOLVED: To provide a lubricating structure of a fuel injection pump capable of preventing an oil feed hole of the fuel injection pump from displacing from an oil feed hole of an attachment flange portion when mounting the fuel injection pump and further improving the reliability against lubricating oil leakage from a seal portion of the oil feed hole connection part. SOLUTION: The lubricating structure of the fuel injection pump includes the attachment portion for the fuel injection pump 8 formed in a cylinder block 2 and a lubricating oil passage extending through the attachment portion so as to communicate a main gallery 31 and a driving section of the fuel injection pump 8 with each other. In the lubricating structure, pin holes 2e, 42 are arranged face to face in abutment surfaces of the cylinder block 2 and the fuel injection pump 8. The pin holes 2e, 42 are aligned with the lubricating oil passage. A pin 43 formed in a tubular shape is inserted in the pin holes 2e, 42. COPYRIGHT: (C)2008,JPO&INPIT
