PROBLEM TO BE SOLVED: To provide a cut-off piece composed of a flexible material as a whole, inexpensive with high performance, dispensing with replacement of parts over a long period of time and prevented from vibrating itself to make a loud sound. SOLUTION: This cut-off piece has a support part protrusively provided with a piece shaft mounted to a spindle, at the center of one face of a disc-like body, and a packing part extended on the other face side of the support part to block a passage in a faucet body. Both the support part and packing part are composed of a polymer with rubber elasticity at an ordinary temperature, and the support part has at least one selected from a recessed hole, a recessed groove, a protrusion and a communicating hole to form a water passage on its outer peripheral surface.
