Intake device for engine

An intake device for an engine comprising:

• a carburetor section and an air cleaner section connected upstream of the carburetor section,
• wherein the carburetor section includes a body having an intake passage which has an opening communicating with the air cleaner section and a choke valve located within the intake passage near the opening, the choke valve being a butterfly valve having a plate-like valve body,
• wherein the air cleaner section includes an air filter, an air-flow chamber provided between the air filter and the intake passage, and a reverse-flow restriction surface provided within the air-flow chamber, the reverse-flow restriction surface being spaced from the opening of the intake passage and facing the entire opening to form a space between the opening and the reverse-flow restriction surface,
• wherein the air cleaner section further includes a plate-like partition having surfaces exposed to the air-flow chamber and extending from a location near an air-cleaner side periphery of the valve body of the choke valve in the full-open position to at least a location near the reverse-flow restriction surface so as to continue the periphery, and
• wherein the air cleaner section further includes a bridge which extends from at least one of the surfaces of the plate-like partition and is coupled to the body of the carburetor section near the opening of the intake passage.
