摘要： A variable valve timing control device includes a rotation member for opening or closing a valve, a rotation transmission member engaged with the rotation member to be relatively rotatable, a vane provided on either one of the rotation member or the rotation transmission member, a hydraulic chamber formed between the rotation member and the rotation transmission member and including an advance angle chamber and a retarded angle chamber, the advance angle chamber and the retarded angle chamber being formed by dividing the hydraulic chamber by the vane, a first hydraulic passage for supplying and discharging a fluid to the advance angle chamber, and a second hydraulic passage for supplying and discharging the fluid to the retarded angle chamber. The vane includes a surface hardness determined to be higher than a surface hardness of a sliding surface of the rotation member or the rotation transmission member for sliding the vane.

摘要： A valve timing control apparatus includes a locking mechanism that can minimize the accumulation of foreign material in a concave engagement part, can minimize the penetration of foreign material to the sliding parts of a locking member, and can reduce the sliding resistance of the locking member. A locking mechanism is provided with a sliding groove provided to an outer rotor; a locking member for sliding along the sliding groove; and a concave engagement part that is provided to the inner rotor, for engaging with the locking member in a state in which the phase of relative rotation is a lock phase, and has an inlet port for introducing hydraulic fluid. Flow channels for hydraulic fluid are provided to at least one of the sliding groove and the locking member, are formed along the sliding direction of the locking member, and are communicatingly connected to the concave engagement part.

摘要： A valve timing control apparatus is provided having a locking mechanism that can minimize the accumulation of foreign material in a concave engagement part, can minimize the penetration of foreign material to the sliding parts of a locking member, and can reduce the sliding resistance of the locking member. A locking mechanism (5) is provided with a sliding groove (52) provided to an outer rotor (2); a locking member (53) capable of sliding along the sliding groove (52); and a concave engagement part (51) that is provided to the inner rotor (3), is formed to be capable of engaging with the locking member (53) in a state in which the phase of relative rotation is a lock phase, and has an inlet port (58) capable of introducing hydraulic fluid. Flow channels (57) for hydraulic fluid are provided to at least one of the sliding groove (52) and the locking member (53), are formed along the sliding direction of the locking member (53), and are communicatingly connected to the concave engagement part (51).
