A switching valve has a cylindrical housing including a bore, an inlet port, a first inlet-outlet port, and a second inlet-outlet port which open to the hollow. A valve member slidably disposed in the bore has a ringed groove around its periphery. The valve member can open or block a portion between the groove and the first inlet-outlet port and a portion between the groove and the second inlet-outlet port. The groove formed outside the valve member always communicates with the inlet port and can communicate with the first and second inlet-outlet ports. A single drain port is formed within the valve member so that the single drain port can communicate with the first and second inlet-outlet ports. The valve member is caused to slide by a solenoid.
