SOLUTION: An internal combustion engine 30 is arranged on the drive wheel side of a unit 20, a lower part is opened and extended while a forward part 20a of the unit case 20 is slightly curved from the left side to the rear side, a bulkhead 42b is formed above a cylinder heat cover 35 of the internal combustion engine 30, and an opening directed downward from the forward part 20a to the bulkhead 42b is covered from the lower side by an air cleaner case cover 43 to constitute the air cleaner case. A separate air cleaner for exclusive use from the unit case 20 need not be manufactured or arranged, to reduce the number of part items and to simplify the assembly work.
