Claims

[Scope of utility model registration request]

In a throttle valve structure provided on the downstream side of a barrel in a throttle body installed in an electronic fuel injection device on the upstream side, a first throttle valve is mounted coaxially from both sides with respect to a first throttle shaft to which a first throttle valve is fixedly installed. A second slot shaft that can be rotated relative to the first slot,
A throttle valve structure characterized in that a second throttle valve is fixedly fitted to the throttle valve.
