。A throttle valve 4 controls the amount of air flowing through the intake passage 2 passing through the carburetor body 1, and a throttle valve 4 rotates synchronously with the throttle valve 4 and is biased by a throttle valve return spring 7 with a force in the direction of closing the throttle valve. A compression chamber 11 and an atmospheric chamber 13 are formed by the throttle valve lever 5 and the partition body 9.
The compression chamber 11 is divided into a compression pressure release passage 14 equipped with a check valve 16 for releasing the compressed air in the compression chamber 11 to the atmosphere, and a leak passage 18 equipped with a control jet 17.
and a dashpot 8 compressed with a spring 19 that presses the partition body 9 toward the atmospheric chamber side, and the dashpot 8 and the throttle valve lever 5 are engaged with each other when the engine is idling, and the throttle valve lever of the partition body 9 is compressed. The idling opening of the throttle valve 4 is maintained by setting the pressing force on the throttle valve 5 to be larger than the pressing force on the partitioning body 9 of the throttle valve lever 5, and on the other hand, the pressing force of the throttle valve lever 5 on the partitioning body 9 is divided A throttle valve return device for a carburetor, characterized in that the pressing force of the body 9 against the throttle valve lever 5 is greater than that to permanently hold the throttle valve 4 below the idling opening.
