Claims

[Scope of Claim for Utility Model Registration] (1) A throttle valve 24 that is displaced to control the flow cross-sectional area of the intake passage 16 of the carburetor 10, and a rotating shaft 7.
A throttle lever 56 rotates integrally with the rotating shaft 76 around an axis of 6 and swings when operated by an operator, and a throttle lever 56 that transmits the displacement of the throttle lever 56 to the throttle valve 24 and rotates the throttle valve 24. 24; and brakes 70, 80, 85 that decelerate the rotation of the rotating shaft 76 in the closing direction of the throttle valve 24. (2) The throttle device for a carburetor according to claim 1, wherein the brakes 70, 80, and 85 are friction materials provided on a rotating sliding portion of the rotating shaft 76. (3) The brakes 70, 80, 85 include a liquid chamber 70 filled with a viscous liquid 85, and a liquid chamber 70 filled with a viscous liquid 85.
2. The throttle device for a carburetor according to claim 1, further comprising a vane 80 disposed within the rotary shaft 76 and rotating integrally with the rotary shaft 76.
