Claims

[Claims for Utility Model Registration] A main gear fixed to a rotating camshaft, and a sub-gear that overlaps the main gear and is movable relative to the main gear in the circumferential direction above the camshaft. , a camshaft equipped with a scissor gear consisting of the main gear, the sub-gear, and a spring that connects both gears via pins fixed to each, the camshaft is provided with a shaft oil passage extending in the axial direction of the camshaft at the center; , at least two branch passages are provided that branch from the shaft oil passage, extend outward in the shaft radial direction, and open at the main gear fitting portion and the sub gear fitting portion of the camshaft, and the main gear and the sub gear are communicated with the branch passage. Two gear oil passages are provided in each of the pin fitting holes, and further, pin oil passages are formed in both of the pins, communicating with the gear oil passages and opening in the spring fitting portions of the pins. Camshaft with scissor gear.
