PROBLEM TO BE SOLVED: To provide a multi-directional valve capable of setting the size of the diameter of a disk small even when a switching structure of a passage is complicated, thereby making the entire size of the valve small, and reducing sliding torque of the disk. SOLUTION: The multi-directional valve has a casing 1 provided with multiple ports, a spacer 5 fixedly positioned on the base inside the casing 1, a fixed disk 6 positioned above the spacer 5, and a rotating disk 7 positioned above the fixed disk 6. The multi-directional disk switches the communication passage at every stop phase of the rotating disk 7, and the switching passages provided on each of the base of the inside of the casing 1, the spacer 5, the fixed disk 6 and the rotating disk 7 are formed divided into a plurality of layers x and y in the radial direction of the disks 6 and 7.
