PROBLEM TO BE SOLVED: To provide the subject support structure having resolved such problems that, as to conventional structure for a planting section to be linked with a rice transplanter body, the built-in shaft is of cantilever-supported type, therefore the construction become inevitably large for securing its mechanical strength, furthermore, because of using bearings, the number of part items increase as well, and the construction as a whole is complicated, resulting in higher cost and heavier weight as a whole, and besides, assemblability is not favorable. SOLUTION: This support structure for a planting frame is such that the planting frame 92 is arranged with a connective member 260 extending forward, the rear portion of a lift link mechanism 10 is furnished with a hitch 94, and a rolling support shaft 176 is inserted into the hitch 94 and the connective member 260, and the front wall of the hitch 94 is provided with a slot 94d.
