<p><P>PROBLEM TO BE SOLVED: To provide constitution capable of enhancing the flexibility of an attaching position for a fuel pump driving cam, in an assembly camshaft assembled with the fuel pump driving cam for driving a fuel pump onto a camshaft main body. <P>SOLUTION: The flexibility of the attaching position for the fuel pump driving cam 115 is enhanced by providing each valve system cam 130R as a separate member separated from the camshaft main body 30R, and by attaching the valve system cams 130R, 130R, etc. from an axial outside of the camshaft main body 30R, after attaching the fuel pump driving cam 115 to the camshaft main body 30R. The each valve system cam 130R is formed of a solid phase sintered material, and the fuel pump driving cam 115 is formed of a liquid phase sintered material. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
