  "textContent": "An air cleaner in a two-stroke engine having an air supply passage that is connected midway of a scavenging passage communicating a scavenging port provided in a side portion of a cylinder with a crank chamber and that supplies leading air from the air cleaner to the scavenging passage, and an air/fuel mixture supply passage supplying air/fuel mixture created in a carburetor to the crank chamber. The air cleaner includes: a first air passage and a second air passage arranged in parallel, the first air passage being communicated with the air supply passage and the second air passage being communicated with the air/fuel mixture supply passage; and a choke valve opening and closing both of the first air passage and the second air passage of the air cleaner. The choke valve has a pivot axis and a pivotable valve member pivoting about the pivot axis to open and close respective inlet openings of the first air passage and the second air passage. One of the first air passage and the second air passage that is located closer to the pivot axis has an inlet opening flattened along a pivoting edge of the valve member.",
