A control valve 1 includes: an inlet port 110 for introducing a refrigerant from an upstream side; outlet ports 112 and 114 each for delivering the refrigerant toward a downstream side; a body 104 having valve holes 120 and 144 for communicating the inlet port 110 and the outlet ports 112 and 114 together, respectively; valve elements 130 and 132 for opening and closing valve sections by contacting and leaving the valve holes 120 and 144, respectively; a stepping motor having a rotor 172 for driving the valve elements 130 and 132 in the opening and closing directions of the valve sections; and a valve actuating member 134 that rotates with the rotor 172, and that drives the valve elements 130 and 132 in the opening and closing directions of the valve sections by converting a rotational movement of the rotor 172 around the axis line thereof into a translational movement of the valve actuating member in the axis line direction. The valve actuating member 134 is supported by the rotor so as to be capable of making a translational movement of the valve actuating member in the axial direction with respect to the rotor 172, while a rotational movement with respect to the rotor 172 is regulated. |
