PRIME MOVER PORTION STRUCTURE OF WORKING MACHINE

摘要

PROBLEM TO BE SOLVED: To allow an engine hood to be opened without removal of an air cleaner of a suction pipe and an engine and to realize cost reduction. SOLUTION: A prime mover portion structure of a working machine includes a rockably openable/closable engine hood 21 and an air cleaner 23 for an engine supported by the engine hood 21. A connection part 35 is provided to a suction pipe 27 for connecting the air cleaner 23 for an engine to an engine 3, and connects an air cleaner side portion 27a and an engine side portion 27b so as to be relatively rotatable around a central axis identical with an opening/closing central axis P of the engine hood 21 so that the air cleaner side portion 27a of the suction pipe 27 relatively rotates with the engine hood 21 with respect to the engine side portion 27b of the suction pipe 27.
