Patent ID: 7322326

Claim:
A valve timing control apparatus for controlling at least one of an intake valve and an exhaust valve of an internal combustion engine having a driving shaft, the valve timing control apparatus comprising: a driven shaft for actuating the at least one of the intake valve and the exhaust valve; a housing member for rotating together with one of the driven shaft and the driving shaft; and a rotor member accommodated coaxially in the housing member for rotating together with an other of the driven shaft and the driving shaft, the rotor member being rotatable with respect to the housing member in a predetermined angular range, wherein the rotor member includes a rotor vane that has a thick portion, which constructs a circumferential part of the rotor vane, and a thin portion, which constructs a circumferential part of the rotor vane other than the thick portion, the thick portion is greater than the thin portion in thickness with respect to a radial direction of the rotor vane, the rotor vane has one end surface defining an engage hole in which the other of the driven shaft and the driving shaft engages, the rotor vane has an other end surface defining a press-insertion hole, the rotor member further includes a bushing vane, in a substantially cylindrical shape, having one end, the one end of the bushing vane is connectable to the rotor vane through the press-insertion hole with a compression margin relative to the thin portion, and the one end of the bushing vane is connectable to the rotor vane through the press-insertion hole without a compression margin relative to the thick portion.
