To improve operability of a water discharge pipe in a faucet for rotatably installing another water discharge pipe on the tip of the water discharge pipe installed in a faucet body.
In this faucet A for rotatably installing the water discharge pipe B in the faucet body 1 by a first joining member C and rotatably installing a second water discharge pipe 16 for arranging a water discharge port 17 on the tip to a first water discharge pipe 9 by a second joining member D in the water discharge pipe B, rotary operation force of the first water discharge pipe 9 to the faucet body 1 and rotary operation force of the second water discharge pipe 16 to the first water discharge pipe 9 are made different between the respective joining members C and D. The rotary operation force of the second water discharge pipe 16 to the first water discharge pipe 9 is reduced more than the rotary operation force of the first water discharge pipe 9 to the faucet body 1.
