とを特徴とするエアブリード装置。 A main body having an intake passage; a throttle valve provided on the main body so as to be slidable in a direction perpendicular to the intake passage to open and close the intake passage; and a throttle valve provided on the main body coaxially with and facing the throttle valve. The main jet has a plurality of air bleed holes arranged radially around a needle jet formed in the center thereof, and a main jet that is slidably inserted into the needle jet and has an elastic hole extending toward one side in the radial direction of the needle jet. A tapered metering needle attached to the tip of the throttle valve so as to be energized, communicates with the air bleed hole, and controls the amount of air supplied to the air bleed hole according to engine operating conditions. In a variable bench lily type carburetor equipped with a bleed amount control device, one of the plurality of air bleed holes provided radially in the needle jet is located on the one side where the metering needle is elastically biased. An air bleed device characterized by having a diameter larger than that of the device located on the other side.
