A valve timing control apparatus includes a driven shaft for actuating an intake valve and/or an exhaust valve of an engine. A housing member rotates together with a driving shaft of the engine. A rotor member is accommodated coaxially in the housing member for rotating together with the driven shaft. The rotor member is rotatable with respect to the housing member. The rotor member includes a rotor vane that circumferentially has a thick portion and a thin portion. The thick portion is greater than the thin portion in radial thickness. The rotor member further includes a bushing vane, in a substantially cylindrical shape, having one end. The one end is connectable to the rotor vane through a press-insertion hole with a compression margin relative to the thin portion. The one end is connectable to the rotor vane through a press-insertion hole without a compression margin relative to the thick portion.
