Claims

[Scope of utility model registration request]

a main intake passage with a butterfly throttle valve is disposed horizontally, upstream of the butterfly throttle valve of the main intake passage, intersects with the main intake passage depending on the intake air flow rate in the main intake passage; A sliding valve that moves forward and backward to form a variable bench lily is disposed, protrudes into the variable bench lily portion of the main intake passage so that a main fuel nozzle opens, and has a bottom surface having an arcuate cross section on a lower end surface of the sliding valve. In the horizontal variable bench lily carburetor in which a groove is formed in the direction of the main intake passage, a rectifier plate that covers the groove is attached to the lower end surface of the slide valve, and when the slide valve is at the minimum opening degree, the A horizontal variable bench lily carburetor, characterized in that a main fuel nozzle passes through the rectifier plate, and an upper end opening surface is located above the rectifier plate.
