PROBLEM TO BE SOLVED: To shorten a waiting time until the next beverage pouring by making foams remaining in a nozzle completely drop in a short period of time. SOLUTION: On a cock body 10, a first air hole 60 which can introduce the outside air into a beer pouring nozzle 14, and a second air hole 62 which can introduce the outside air into a foam pouring nozzle 16 are formed. On the outer periphery of a sleeve 24 which is inserted in a beer feeding passage 12, a first annular groove 64 which communicates the first air hole 60 with the beer pouring nozzle 14, and a second annular groove 66 which communicates the second air hole 62 with the foam pouring nozzle 16 before the operation of a lever 18 are peripherally provided. At the time of a beer pouring operation of the lever 18, the communication between the first annular groove 64 and the first air hole 60 is shut off, and at the same time, the communication between the second annular groove 66 and the second air hole 62 does not come to shut off. At the time of a foam post-pouring operation of the lever 18, the communication between the second annular groove 66 and the second air hole 62 is shut off, and at the same time, the communication between the first annular groove 64 and the first air hole 60 does not come to shut off.
