Claims

[Scope of utility model registration request]

A throttle valve lever 3, which is fixed to the rotating shaft of a butterfly-shaped throttle valve 2 disposed in the intake passage 1 of the engine and is biased in a direction in which the throttle valve 2 opens, is biased in a direction in which the throttle valve 2 is closed. The throttle valve 2 contacts in the circumferential direction the accelerator lever 4 that rotates when the accelerator is operated, and the accelerator is operated following the accelerator lever 4, and the throttle valve 2 is moved in a direction in which the throttle valve 2 is closed relative to the rotational position at which the accelerator is operated. In the computer-controlled butterfly-shaped throttle valve opening control device, the butterfly-shaped throttle valve 2
When the throttle valve lever 3 is unable to rotate following the accelerator lever 4 due to the bite between the inner wall surface of the intake passage 1 and the inner wall surface of the intake passage 1, In order to release the interlock between the butterfly-shaped throttle valve 2 and the inner wall surface of the intake passage 1 by rotation, a cam surface 4-2 is formed on the outer peripheral surface of the accelerator lever 4, and a cam surface 4-2 is formed on the outer peripheral surface of the accelerator lever 4, and the butterfly-shaped throttle valve When the valve 2 is opened at a small opening, a swinging lever 14 is disposed in the opening direction of the throttle valve 2 to lightly abut the throttle valve lever 3, so that the butterfly-shaped throttle valve 2 and the inner wall surface of the intake passage 1 engage with each other. Therefore, when the accelerator lever 4 rotates relative to the throttle valve lever 3 in the opening direction of the throttle valve 2, the rocking lever 14 follows the cam surface 4-2 and opens the butterfly-shaped throttle. By forcibly opening the valve 2 to a certain degree, the butterfly-shaped throttle valve 2
1. A butterfly-shaped throttle valve opening degree control device, characterized in that the opening degree control device for a butterfly-shaped throttle valve is released from interlocking between the inner wall surface of the intake passage 1 and the inner wall surface of the intake passage 1.
