ルブの開閉機構。 In a throttle valve opening/closing mechanism that includes a throttle drum connected to a return spring for closing the throttle valve and a throttle opener,
a lever operated by the throttle opener is provided fixed relatively to the throttle shaft;
The throttle drum is rotatably provided with respect to the throttle shaft, and the throttle drum has a contact portion that comes into contact with the lever when the throttle drum is rotated in a direction in which the throttle valve opens. A spring is provided between the lever and the throttle drum, and the spring biases the lever in a direction in which it comes into contact with the corresponding contact portion, and the spring applies the torque applied to the lever by the return spring to the throttle drum. A throttle valve opening/closing mechanism characterized by having a spring force smaller than torque.
