PROBLEM TO BE SOLVED: To provide a silent and highly reliable selector valve capable of high-speed rotation by changing a rotational motion to a linear motion via an oscillating motion. SOLUTION: The channel selector valve comprises a valve housing with an air intake, an air vent and a plurality of outlets, a plurality of cylinders with an air supply part communicating with the air intake and a ventilation part communicating with the air vent, disposed in the valve housing corresponding to the plurality of outlets respectively, a valve mechanism disposed inside each cylinder for selecting a channel as pressed in either state of communication: the state of communication between the air supply part and the outlet, or the state of communication between the ventilation part and the outlet, an oscillation body with restrained rotation, attached to the valve housing oscillatably in the direction of pressing the valve mechanisms, and a rotary body for transmitting the rotation motion to the oscillation body. The oscillation body converts the rotational motion to the oscillating motion together with the rotary body, and the state of communication is switched by the oscillating motion to press the valve mechanisms inside the cylinders one after another.
