WORKING VEHICLE

PROBLEM TO BE SOLVED: To solve a problem wherein, in a working vehicle configured so that the PTO power from a main and sub axles driving device and a main axle driving device is transmitted to the main axle driving device in a connecting and disconnecting manner so as to change over between the two-wheel drive and the four-wheel drive, dedicated cases for particular specifications must be fabricated in order to make appropriate the rotating attitudes of a body case of the sub axle driving device and an input case accommodating the input part of the PTO power, leading to an increase in the management costs. SOLUTION: The armoring of the front axle driving device 2 is composed of: the body case 74 supporting the front axle 4; and the input case 73 to accommodate the input part 50 of the PTO power, the input case 73 is butted and coupled to the body case 74 to be freely decoupled, and the outer edges of the joins 73c and 74c of the butt coupling part 101 are formed in the same regular polygonal shape or in point symmetry, and thereby coupling is generated in which the two joins 73c and 74c become identical at least one time as viewed from the butting direction while they make relative rotation to 180 degrees in the butted condition.
