PROBLEM TO BE SOLVED: To mount a temperature-sensitive actuating valve in a state that an air cleaner is compacted. SOLUTION: The interior of an air cleaner 18 is horizontally partitioned into the dirty side 34 and the clean side 35 by a longitudinally long air cleaner element 33. The extension part 36 of an intake duct 20 extending from a front is long extended to the internal part of the dirty side 34, and a temperature- sensitive actuating valve 26 is attached in the clean side 35 approximately in parallel to the air cleaner element 33. A bypass tube 27 extending from the front end thereof through a front wall 47 to a front is approximately in parallel to a connecting tube 21 connected to a carburetor 22 by extending from the front wall 47 to a front, and a front end is connected to the bypass passage of the carbureter 22. |
