摘要： A valve opening-closing timing control device includes a valve case in which an inner space is formed in a direction along a rotational axis, and a valve unit accommodated in the inner space so as to be coaxial with the rotation axis and controlling fluid to and from an advance chamber and a retard chamber. The valve unit includes a check valve on an upstream side to which fluid is supplied. The check valve includes a valve seat in which a flow passage hole through which the fluid flows is formed, and a valve body including a closing portion that can close the flow passage hole. The valve seat includes a first projection portion to surround the flow passage hole. The check valve is closed by the closing portion contacting against the first projection portion, and is opened by the closing portion being separated from the first projection portion.

摘要： The valve opening/closing timing control device includes: the driving rotating body; the driven rotating body; an advancing chamber and a retarding chamber formed by partitioning a fluid pressure chamber between the driving and driven rotating bodies; and a phase control unit supplying pressurized fluid to the advancing or retarding chamber via an advancing channel or a retarding channel penetrating through the driven rotating body. In the driven rotating body, an outer circumferential member and an inner circumferential member are formed integrally/coaxially with each other. The advancing and retarding channel form a predetermined angle. Between every pair of an advancing channel and a retarding channel, a groove portion is formed in one of an inner circumferential surface of the outer circumferential member and an outer circumferential surface of the inner circumferential member, and an elongated protruding portion is formed on the other, at a position that corresponds to the groove portion.
