Claims

[Scope of utility model registration request]

(1) A carburetor throttle valve configured by connecting a throttle lever and an EGR valve body via a connecting arm, and setting the connection point between the throttle lever and the continuous arm away from an extension of the axis of the EGR valve body. In the connection mechanism, one end is EGR
An intermediate pin is provided which is fixed to the valve body and whose other end is attached to the EGR valve side end of the connecting arm.
The length of the intermediate pin is selected so that a line connecting the connecting point between <- and the connecting arm and the connecting point between the intermediate pin and the connecting arm is approximately parallel to the axis of the EGR valve body. Connection mechanism.

(2) A spring is provided that biases the intermediate pin in a direction that cancels out the component force of gravity acting on the EGR valve body in a direction perpendicular to the axis of the EGR valve body, and the elasticity of the spring is set approximately equal to the component force. The coupling mechanism according to claim (1) of utility model registration, characterized in that:
