Abstract: A first housing has a first concave portion that opposes to a vane rotor, and the first concave portion has an inside diameter larger than an inside diameter of a first through hole of the first housing. A boss part of the vane rotor has a first convex portion projected into the first concave portion. A reed valve is arranged between an end surface of the first convex portion and a bottom surface of the first concave portion, and has an outside diameter larger than the inside diameter of the first through hole.

Abstract: In a valve timing adjusting device, a vane rotor includes a second supply oil passage connectable to a first supply oil passage of a second shaft. A check valve is provided between the vane rotor and the second shaft, and permits a flow from the first supply oil passage toward the second supply oil passage and prevents a flow from the second supply oil passage toward the first supply oil passage. A fixing unit is provided between the check valve and the second shaft, and fixes the check valve between the fixing unit and the vane rotor. The fixing unit includes a third supply oil passage which connects the first supply oil passage and the second supply oil passage. A filter is provided for the fixing unit and can capture foreign substances flowing through the third supply oil passage.
