PROBLEM TO BE SOLVED: To dispense with remaking of a fuel injection camshaft into one having the large diameter and to omit an expensive drilling cost for a long thin oil inlet hole by eliminating the need for drilling the long thin oil inlet hole, over the total length of the fuel injection camshaft made of a tough material. SOLUTION: In a pump housing 3, an oil-receiving part 10 is recessed and formed on the upper part peripheral surface 9 of a bearing boss 8. An oil inlet hole 11 for guiding oil in the oil-receiving part 10 to a sub sidary power take-off chamber 4 is formed on the rear wall 7 of the pump housing 3. After a part of oil splash scattering in the pump housing 3 flows to the oil receiving part 10 along the inner side surface of the rear wall 7, it flows into the sub sidary power take-off chamber 4 through the oil introducing hole 11.
