Abstract (en)

[origin: EP2985429A1] To provide a valve opening/closing timing control device where oil leakage is inhibited from occurring, for example, from a gap between members constituting a drive side rotational body while lubrication and abrasion resistance of a slide surface of a housing main body are maintained. The valve opening/closing timing control device includes a housing main body that includes an opening which opens to at least one side in a direction along a rotational axis X and a cover plate closing the opening by making contact with an end surface of the opening, the drive side rotational body rotating synchronously with a crankshaft, and a driven side rotational body housed within the drive side rotational body and defining an advance chamber and a retardation chamber relative to an inner peripheral surface of the housing main body, the driven side rotational body rotating integrally with a camshaft and coaxially with the rotational axis. In addition, the housing main body includes a hard layer formed at least at the inner peripheral surface of the housing main body in a surface thereof excluding the end surface of the opening.
