Abstract:
1. A valve timing control apparatus comprising: a housing that is rotatable synchronously with a crankshaft of an internal combustion engine; a vane rotor that is rotatable synchronously with a camshaft of the internal combustion engine, wherein the vane rotor partitions between an advancing chamber and a retarding chamber in a rotational direction in an inside of the housing, and a rotational phase of the vane rotor relative to the housing is changeable in one of an advancing side and a retarding side by feeding hydraulic fluid, which is supplied from a supply source, into a corresponding one of the advancing chamber and the retarding chamber; and a control valve that controls input and output of the hydraulic fluid relative to the advancing chamber and the retarding chamber, wherein: valve timing of a valve, which is opened or closed by the camshaft, is adjusted by transmission of a torque from the crankshaft; the control valve includes: the valve member includes: an outer peripheral surface, which is guided by a wall surface of the connection passage; and
