摘要 |
A valve timing control system for an internal combustion engine includes a housing having and a cover member mounted thereto, a phase adjusting mechanism accommodated in the housing to hydraulically change the rotation phase of a crankshaft and a camshaft, a supply/discharge rod arranged through a through hole of the cover member and connected to the phase adjusting mechanism, a seal ring engaged with the supply/discharge rod to hermetically seal a clearance between the supply/discharge rod and the phase adjusting mechanism, a taper surface formed on the periphery of the through hole to increase the diameter of the through hole toward the outside of the housing, and a protrusion formed with the cover member in a radially inside area thereof to protrude in the axial direction of the system, wherein the through hole is formed at the protrusion.
