Abstract: A hydraulic oil control valve is coaxially disposed with a rotational axis of a valve timing adjustment device. The hydraulic oil control valve includes a sleeve, a spool, a movement restricting portion, a fixing member. The sleeve includes an inner sleeve and an outer sleeve. The fixing member is fixed to an end portion of the outer sleeve facing the actuator. The fixing member is configured to restrict the inner sleeve from moving in a circumferential direction relative to the outer sleeve and to restrict the inner sleeve and the spool from coming off from the outer sleeve toward the actuator in the axial direction.
