Abstract
A valve timing control device comprises a drive side rotation member for rotating with a crank shaft with synchronization, a driven side rotation member arranged coaxially with the drive side rotation member and slidable therewith, the driven side rotation member rotating with the camshaft, and a rotation phase position adjustment mechanism for adjusting a relative rotation phase between the drive side rotation member and the driven side rotation member by an operating oil. The drive side rotation member and the driven side rotation member form a vertical sliding surface relative to a rotation axis, and an oil reservoir is formed at the driven side rotation member. The oil reservoir is open to the sliding surface and is connected to a drain for the operating oil.
