PROBLEM TO BE SOLVED: To provide a motor-driven selector valve capable of reducing power consumption, causing little noise, reducing the costs of devices and manufacture because of a relatively simple arrangement, and maintaining the sealability of a valve element against an outflow port. SOLUTION: The motor-driven selector valve includes: a stepping motor comprising a can, a stator mounted on the outer periphery of the can, and a rotor or the like disposed in a pressurization chamber on the inner periphery of the can; a rotating valve element loosely fitted around the inner periphery of the rotor in such a way as to be rotatable integrally therewith; and a valve seat member having a valve seat disposed oppositely to one end face of the rotating valve element. The valve seat member has one inflow port and a plurality of outflow ports formed in the seat surface thereof, and the rotating valve element is provided at one end face thereof with a closing projection rotated in sliding contact with the seat surface for alternatively closing either of the plurality of outflow ports according to its rotation stopping position.
