Claims

[Scope of utility model registration request]

In the switching valve, the switching valve includes a shaft portion attached with a valve body and a bearing portion attached to a casing to pivotally support the coaxial portion, and a cylinder that allows rotation of the shaft portion on the inner circumferential surface of the bearing portion. A switching valve structure comprising a drum-shaped sliding surface and a drum-shaped sliding surface formed on the outer peripheral surface of the shaft portion that slides in contact with the cylindrical sliding surface.
