ABSTRACT:
A faucet includes a spout having a shaft portion protruding inwardly from the spout to be rotatably engaged with a boss of the faucet; and two packing members disposed on two opposite sides of the boss having an outer packing member rotatably sealed between an annular shoulder portion of the spout and an outer seat portion of the boss, and having an inner packing member resiliently retained on an inner seat portion of the boss by a tensioning spring jacketed on the shaft portion which is protruded into an interior in the boss, thereby providing a resilient packing between the spout and the faucet for a smooth rotation of the spout for prolonging a service life of the packing members and the spout.
