Abstract
The fuel pump driving structure includes a camshaft and a pump cam member. The camshaft is rotatably supported at an end by a cylinder head. The pump cam member has a fitting hole into which the end of the camshaft is press fitted, and is operatively coupled to a high-pressure fuel pump. The pump cam member includes a pump cam section and a first contact section. The pump cam section has a first lift portion operating the high-pressure fuel pump, and a base circular portion that does not operate the high-pressure fuel pump. The first contact section is in a position offset from a position of the first lift portion with respect to a circumferential direction and contacting a portion of the camshaft in an axial direction at a position radially outward of an external circumferential surface of the one end of the camshaft.
