Abstract (en)

A variable valve timing control device (1) includes a retracting portion (34) accommodating a lock member (80) biased by a spring (81). The variable valve timing control device further includes a spring receiving bore (35) connected to the retracting portion for accommodating the spring and including a guide portion (35a) for guiding the spring in the axial direction, a receiving portion into which a head portion (80a) of the lock member is inserted at a predetermined relative rotation phase, and a fluid passage (25) through which the operation fluid is supplied to or discharged from the receiving portion. A length of the guide portion in the axial direction is larger than each distance formed between windings of the spring adjacent to each other in the axial direction. <IMAGE>
