PROBLEM TO BE SOLVED: To make a carbonated beverage delivery valve for feeding a carbonated beverage from a reservoir container capable of quickly and reliably closing. SOLUTION: The carbonated beverage delivery valve comprises a float chamber 3 having a beverage inlet 25 on a bottom and a beverage passage 12 serving as a beverage outlet on a top respectively, and a float 2a built into the float chamber 3 and designed to close the passage 12 when a quantity of carbon dioxide gas flowing into the float chamber 3 increases. The float 2a comprises a bubble reservoir chamber 16 for capturing the carbon dioxide gas flowing from the inlet 25 into the float chamber 3 via an opening 8 on a lower part and substituting the beverage for the gas for storage, and is designed to move due to a buoyancy occurring by the substitution to have the passage 12 closed. The valve further includes a passage 2f for removing bubbles connected with the uppermost portion of the float 2a and a bubble removing mechanism 23 mounted on the upper end of the passage 2f for discharging the carbon dioxide gas reserved in the bubble reservoir chamber 16 when the float 2a is at a predetermined position.
