Abstract
A hydraulic oil control valve, which is placed along a rotational axis of a valve timing adjusting device, includes a sleeve and a spool configured to slide in an axial direction on an inner side of the sleeve in a radial direction. The sleeve includes: an inner sleeve that has an opening in which a distal end portion of the spool is inserted; and an outer sleeve. In a state where the spool is positioned farthest from an actuator, the distal end portion projects from the opening toward a side that is opposite to the actuator.
