<P>PROBLEM TO BE SOLVED: To provide a motor unit structure of a combine harvester which can bring a dust-preventive function into a state of being exerted properly while a dust-preventive screen can be attached to and detached from a radiator by simple operation. <P>SOLUTION: A sidewall 38 of the motor unit is constituted in a manner that it can be switched over between: a properly-fitted state that it is arranged close to the radiator 16 in the state of having the dust-preventive screen 18 interposed between the sidewall 38 and the radiator 16; and an open state that the same is arranged apart from the radiator 16 and the front side of the radiator 16 is opened. The dust-preventive screen 18 is inserted and fitted in the state that a supporting body 50 is engaged with a rectangular frame-shaped frame body 52 arranged at an outer circumferential part of an air-intake side of the radiator 16. An elastic and deformable sealing material 55 is arranged at the entire circumference of the outer circumferential part of the frame body 52. In the state that the sidewall 38 is switched over to the properly-fitted state, the sidewall 38 presses the sealing material 55. <P>COPYRIGHT: (C)2012,JPO&INPIT |
