PROBLEM TO BE SOLVED: To provide a motor part structure for a working machine, in which a lateral width of a machine body can be set narrow, overheating of an engine can be suppressed, and a frequency of conducting maintenance and inspection work is low.SOLUTION: A motor part structure for a working machine is provided to solve the problem by: arranging an oxidation catalyst device (11) for oxidizing unburned fuel in exhaust gas exhausted from an engine (E) along the longitudinal direction, at a portion above the engine (E) inside a machine body; winding a first belt (27) around a first pulley (25), which is supported by an output shaft (60B) provided at a portion on the inner side of the machine body from the engine (E), and a second pulley (26), which is supported by a winnower shaft (22) provided in a threshing device (3); connecting a tail pipe (30) to an exhaust port (11F) in the rear of the oxidation catalyst device (11); arranging the tail pipe (30) in a downwardly inclined manner toward the rear to face a space formed between the threshing device (3) and a grain tank (5); and bending a portion of the tail pipe (30) opposing to the first belt (27) toward the engine (E) side.SELECTED DRAWING: Figure 7 |
