A flow rate control valve includes: a valve casing forming a fluid passage; a valve seat provided in the fluid passage; a stepping motor; a valve guide stroke-controlled by the stepping motor via a feed screw mechanism; a valve body configured to be placed and separated on and from the valve seat; a connector connecting the valve guide and the valve body so as to allow them to move in an axial direction within a predetermined range; a valve spring biasing the valve body in a closing direction. When closing the valve body, ECU controls the motor to a closed state such that a connection between the valve guide and the valve body by the connector is released, with the valve body being seated on the valve seat, and the valve guide being situated at a non-contact position spaced away from the valve seat.
