Zusammenfassung:PROBLEM TO BE SOLVED: To provide a transmission structure of a working vehicle which enables the positioning and accurate assembling of a coupling onto one transmission shaft only by seeing the appearance without making a mistake in orientation, by making the outside shape of the coupling irregular in the longitudinal direction so as to be able to identify the location of a groove formed in the inner periphery.SOLUTION: This transmission structure of a working vehicle is made by connecting both transmission shafts 27 by fitting a ring 37 into grooves 41 and 39 formed in the outer periphery of one transmission shaft 27 and the inner periphery of the coupling 35, and by spline-fitting the coupling 35 positioned on the shaft 27 into the other transmission shaft. The transmission structure is configured to be able to identify the location of the groove 39 formed in the inner periphery of the coupling 35 by making the outside shape of the coupling 35 irregular in the longitudinal direction.
