摘要:
A valve timing control apparatus includes a partitioning portion in a driven-side rotary member for partitioning the fluid pressure chamber into an advance angle chamber and a retard angle chamber, a restricting member in the driven-side rotary member and projectable and retractable relative to a driving-side rotary member, a restricting recess in the driving-side rotary member and restricting a relative rotational phase to a predetermined range in association with projection of the restricting member therein, a locking member disposed in the driven-side rotary member and projectable and retractable relative to the driving-side rotary member, a locking recess formed in the driving-side rotary member and locking the relative rotational phase to the predetermined phase in association with projection of the locking member therein, a communication passage formed between the restricting member and the locking member, and an urging passage for feeding fluid for projecting the restricting member into the restricting recess.
