Claims

[Claims for Utility Model Registration] 1. A disc made of a non-magnetic material that rotates in synchronization with the rotation of the engine, a swinging member pivotally supported on a fixed side so as to be swingable, and the swinging member. a magnet that is attached to one end and generates an electromagnetic force that causes the swinging member to swing in the rotational direction of the disc in accordance with the rotation of the disc by applying a magnetic field to the disc; a return spring provided between the swinging member and the fixed side so as to suppress swinging in the rotational direction of the disc; and one end pivotally supported on the fixed side so as to be able to swing freely. , and a control member having a cable connected to the engine throttle at the other end and swinging the swinging member in the direction of rotation of the disc via a tension spring in response to the movement of the throttle when starting the engine. and an L-shaped lever that is rotatably supported on the fixed side and rotated via a link in response to the swinging of the swinging member, and converts the circular motion of one end of the L-shaped lever into a linear motion. Alternatively, a fuel cut valve driving device includes a drive mechanism that opens and closes a fuel cut valve provided to close a fuel jet portion of a carburetor. 2 L according to the swinging of the swinging member when the engine is stopped
The fuel cut valve drive according to item 1 above, characterized in that the fuel cut valve is changed from an open state to a closed state and then from a closed state to an open state according to the circular motion of one end of the shaped lever. Device.
