摘要:
A variable valve timing control device includes a driving side rotation member configured to synchronously rotating with a crankshaft, a driven side rotation member positioned coaxially to the driving side rotation member and integrally rotating with a camshaft, an intermediate lock mechanism selectively switching a locked state and an unlocked state, a first electromagnetic valve arranged at a position coaxial to the driving side rotation member and for controlling an supply and draining of an operation fluid relative to the fluid pressure chamber, a second electromagnetic valve positioned being offset from the position coaxial to the driving side rotation member and for controlling a supply and draining of the operation fluid flowing from the camshaft to the intermediate lock mechanism separately from the first electromagnetic valve, and a pump supplying the operation fluid to the first electromagnetic valve and the second electromagnetic valve.
