<P>PROBLEM TO BE SOLVED: To provide a prime mover structure of a working vehicle superior in cooling efficiency of an engine, and easily performing maintenance-inspection. <P>SOLUTION: The problem is solved by configuring the prime mover structure of the working vehicle so as to switch between a cooling state of sucking outside air to the inside from the outside of a filtering body (12) by driving the fan (40) for normal rotation and a dust removing state of blowing off wind to the outside from the inside of the filtering body (12) by driving the fan (40) for reverse rotation, with every predetermined time, by shift control of a hydraulic continuously variable transmission (30), by eccentrically arranging the hydraulic continuously variable transmission (30) outside a rotational locus of the fan (40) when viewed from the rotational axis direction of the fan (40). <P>COPYRIGHT: (C)2012,JPO&INPIT |
