1. A valve timing control device comprising 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 cam shaft, 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, wherein a vertical sliding surface relative to a rotation axis is formed by the drive side rotation member and the driven side rotation member, and an oil reservoir is formed at the driven side rotation member, the oil reservoir being open to the sliding surface and being connected to a drain for the operating oil. |
