<P>PROBLEM TO BE SOLVED: To provide a water supply control valve capable of using a compact motor generating weak power as a driving part for driving an operation shaft and preventing water leakage. Ž<P>SOLUTION: This water supply control valve 24 is constituted by extending the operation shaft 56 onto a main valve 36 side through a flow-out water passage 34 on a secondary side from a valve body 30 to operate the main valve 36 on a flow-out water passage 34 side through a pilot valve 45 by the operation shaft 56. A section between the operation shaft 56 and the valve body 30 is sealed by an O-ring 86, and the water leaking through the O-ring 86 is led through a driving channel and is detected by a water leakage sensor to close the main valve 36 automatically.
