Lubricant supply device for auxiliary machine of engine

A lubricant supply device for an auxiliary machine of an engine, wherein the auxiliary machine is a high-pressure fuel pump which has a plunger as a driven member and generating high-pressure fuel to be supplied to a fuel injector of the engine, comprising:

• a cam formed at one end of a cam shaft rotatably supported by a cylinder head, the cam extending outside of the cylinder head;
• a housing, for storing the auxiliary machine, attached to an attaching surface formed at an end of the cylinder head, the housing holding a driven member driven by the cam and having a cam storage space for storing the cam;
• a lubricant hole formed on the attaching surface through which lubricant is supplied from a lubricant passage formed in the cylinder head to the cam storage space;
• and
• a metal gasket positioned between the attaching surface and the housing, the metal gasket sealing the cam storage space and outside, wherein
• the metal gasket has a hole for communicating with the lubricant hole and a slit communicating between the hole and the cam storage space.
