PROBLEM TO BE SOLVED: To provide a lubricating oil feeding structure capable of feeding a proper amount of a lubricating oil to the portions of a valve gear which are requested to receive the supply of the lubricating oil. SOLUTION: This lubricating oil feeding structure 10 comprises a camshaft inner passage 11, a supply hole 12, a receiving groove 13, a cam holer inner passage 14, and a jet nozzle 15. By the lubricating oil feeding structure 10 thus formed, since the supply hole 12 is allowed to communicate with the receiving groove 13 only when a cam 41 is within a rotating angle range when coming into contact with a roller follower 52, the supplied amount and the supply timing of the lubricating oil can be controlled by the rotation of the cam 31. As a result, the lubricating oil of a proper amount can be supplied to the portions of the valve gear which are requested to receive the supply of the lubricating oil. COPYRIGHT: (C)2005,JPO&NCIPI |
