Claims

[Scope of utility model registration request]

a throttle body in which a throttle chamber is formed; a valve shaft that diametrically passes through the throttle chamber of the throttle body and is rotatably provided on the throttle body; a valve plate that opens and closes the throttle chamber by externally rotating the proximal end of the valve plate;
a valve shaft-side lever that is provided on the tip side of the valve stem and rotates integrally with the valve stem; and a lever that is located on the tip side of the valve stem and is attached to the throttle body to detect the opening degree of the valve plate. A throttle valve device comprising: a throttle sensor body, which is mounted on the throttle sensor body and is provided with a rotation shaft; and a sensor-side lever, which is integrally provided on the throttle sensor body with the rotation shaft and engages with the valve shaft-side lever. The valve shaft side lever and the sensor side lever include a first engaging portion that engages with each other when the valve shaft rotates in one direction, and a first engaging portion that engages with each other when the valve shaft rotates in the other direction. and a second engaging portion that engages with each other.
