Abstract
A valve timing controller includes a reed valve interposed between an end surface of a vane rotor and an end surface of a driven shaft. The reed valve has a fixed part, a first reed part and a second reed part. Each of the first reed part and the second reed part has each lower limit pressure for allowing working oil to flow from a first supply passage to a second supply passage. The lower limit pressure of the first reed part is different from the lower limit pressure of the second reed part.
