Abstract:
1. A valve timing control system for an internal combustion engine, comprising: a driving member to which a rotational force is transmitted from a crankshaft; a driven member rotatable with a cam shaft as a single member; a phase changing mechanism disposed between said driving member and said driven member to vary a relative rotational phase between said driving member and said driven member within an angular range; a projecting member disposed to one of side of said driving member and side of said driven member and movable forward and rearward; a contacting section formed at the other of the side of said driving member and the side of said driven member and contactable with said projecting member when said projecting member is moved forward so as to restrict relative rotational positions of said driving member and said driven member; a releasing mechanism for moving said projecting member rearward in accordance with an engine operating condition so as to release the restriction for the relative rotational positions upon contacting between said projecting member and said contacting section; and a position adjusting device for adjusting and fixing relative positions of said projecting member and said contacting section.
