To prevent inclination of a cleaning pin provided integrally with a spring energizing a valve element according to compression of the spring.

In a self-closing faucet in which a valve element is mounted so as to be movable forward and backward within a pressure chamber provided within a flow passage formed from an inflow port to an outflow port, the valve element is driven by an operating shaft interlocking with an operation part, a spring energizing in the operation part direction is provided on the operating shaft, a spring energizing the valve element in the operation part direction is provided within the pressure chamber, a small hole communicated with an inflow port is formed at the center part at an inflow port side end part, a cleaning pin slightly smaller than the hole diameter is freely slidably inserted within the small hole and the cleaning pin is formed by being inflected from a winding end part on the valve element side of the spring to a winding center part and being integrally extended from the center part to the small hole, an inflection point of the winding end part is located at the outside of the winding.
