Abstract
A variable valve timing control device includes a rotor member integrally connected to either one of a camshaft and a crankshaft, a housing member connected to either one of the crankshaft and the camshaft via a driving force transmitting member and assembled to the rotor member so as to be rotatable relative thereto, a vane, a fluid pressure chamber divided into an advanced angle chamber and a retarded angle chamber by the vane, and a sensor wheel assembled to either one of the rotor member and the housing member and including a projecting portion for detecting a rotational angle of the rotor member or the housing member by using a sensor provided adjacent to the sensor wheel. The sensor wheel includes at least one reference hole for determining a position of the projecting portion in a circumferential direction of the sensor wheel.
