Abstract
To provide a multi-way selector valve properly used for a vehicle, with a smooth flow path switching operation even in case of a large pressure difference between the inside and outside of a valve body, a reduced refrigerant passing noise at a time of switching a flow path, and an easy flow path switching operation, the multi-way selector valve includes a valve bodyrotated by a flow path switching actuator, and a valve main bodyrotatably holding the valve body, the flow path switching actuator is a stepping motorincluding a rotorplaced on the inner peripheral side of a canand a statorplaced on an outer periphery of the can, and a planetary gear type speed reduction mechanismis inserted between the rotorof the stepping motorand the valve body
