Abstract: An oil control valve has a housing and a spool valve that is arranged in the housing and is movable in the axial direction. The movement range of the spool valve includes a first area and a second area. In the first area, a port that is connected to a lock mechanism opens to prevent the movement of a variable valve timing mechanism through drainage of oil from the lock mechanism. In the second area, oil is supplied and drained to and from the variable valve timing mechanism through a passage inside the spool valve. The first area exists at a position separated from the second area in the movement range.
