Abstract:
A valve timing control device comprising:a cam shaft rotatably assembled with a cylinder head of an engine;a rotational transmitting member mounted around the peripheral surface of the cam shaft so as to rotate relative thereto within a predetermined range for transmitting a rotational power from a crank pulley;a plurality of vanes provided on the cam shaft or the rotational transmitting member;fluid chambers formed between the cam shaft and the rotational transmitting member and separated into advancing chambers and delaying chambers by the vanes;a first fluid passage for feeding and discharging a fluid to and from the advancing chambers;a second fluid passage for feeding and discharging a fluid to and from the delaying chambers;a retracting bore formed in the rotational transmitting member and accommodating a locking pin and a spring to act to the locking pin;a plate supporting one end of the spring, the plate engaging with a groove which penetrates in the radial direction of the retracting bore;a receiving bore formed on the cam shaft; anda third fluid passage for feeding to the receiving bore, wherein the rotational transmitting member includes an external rotor having the retracting bore and a plate member which is connected to the external rotor; and the groove has an opening at a connecting portion between the external rotor and the plate member such that the plate member prevents the plate from coming out after the plate is inserted in the groove.
