VALVE OPENING AND CLOSING TIMING CONTROL DEVICE

Abstract: a valve opening and closing timing control device includes a drive-side rotating body that rotates synchronously with a crankshaft of an internal combustion engine about a rotation axis, a driven-side rotating body that is disposed coaxially with the rotation axis and inside the drive-side rotating body, and rotates integrally with a camshaft for opening and closing a valve of the internal combustion engine, a phase adjustment mechanism that includes plural gears for reducing a driving rotational force of an electric motor and sets a relative rotational phase between the drive-side rotating body and the driven-side rotating body, a lubricating oil supply unit that supplies lubricating oil to the phase adjustment mechanism from outside, and an oil discharge control unit that performs oil discharge control of discharging lubricating oil by changing the relative rotational phase by driving the electric motor in accordance with stop control of stopping the internal combustion engine.
