A water mixing cock has a noise-preventing structure and comprises a fixed plate, an opposing movable plate valve, a hollow chamber in the movable plate valve, a valve operator for rotating the movable plate valve so that either hot or cold or mixed water is allowed to flow through the hollow chamber, a discharge water passage in communication with the hollow chamber, and a variable escape groove for communicating the hollow chamber and the discharge water passage with each other only when hot water is allowed to flow through the hollow chamber. The noise-preventing structure is a sound arresting member disposed in an inlet portion of the movable plate valve in such a manner that noise occurring when the movable plate valve is rotated by the valve operator is minimized.
