Abstract:
1. A valve timing control apparatus comprising: a drive-side rotor rotatable in synchronism with a crankshaft of an internal combustion engine; a driven-side rotor disposed coaxially relative to the drive-side rotor and rotatable in synchronism with a valve opening/closing cam shaft of the internal combustion engine; a fluid pressure chamber formed by said drive-side rotor and said drive-side rotor; a partitioning portion provided in at least one of said drive-side rotor and said driven-side rotor for partitioning said fluid pressure chamber into an advanced angle chamber and a retarded angle chamber; a locking mechanism including; said locking mechanism restraining a relative rotational phase of said driven-side rotor relative to said drive-side rotor when said locking member is retained within said locking groove; and a restricting mechanism including; said restricting mechanism restricting said relative rotational phase within a predetermined range when said restricting member projects into said restricting groove.
