インジエクター。[Scope of Claim for Utility Model Registration] (1) A plunger is fitted into the inner hole of the barrel so as to be movable in the axial direction, a body is attached to the barrel, and a tappet is fitted into the inner hole of the body so as to be movable in the axial direction. In a unit injector for a diesel engine fuel injection device in which the plunger is brought into contact with a camshaft via the tappet, lubricating oil is transferred between the body and the tappet by axial movement of the plunger and the tappet. A unit injector for a fuel injection device for a diesel engine, characterized in that an oil passage for supplying oil to a surface and a sliding surface between the barrel and the plunger is provided in a flange-like pressure part of the body. (2) Fit a plunger into the inner hole of the barrel so that it can move in the axial direction, attach a body to the barrel, fit a tappet into the inner hole of the body so that it can move in the axial direction, and connect the plunger to the tappet. In a unit injector of a diesel engine fuel injection device that is brought into contact with a camshaft through a camshaft, the axial movement of the plunger causes lubricating oil to be transferred to the sliding surfaces between the body and the tappet and between the barrel and the plunger. 1. A unit injector for a fuel injection device for a diesel engine, characterized in that an oil passage for supplying oil to a surface of the body is provided to communicate with the thick flange-like part of the body, the barrel, and the flange at the time of maximum lift.
