PROBLEM TO BE SOLVED: To simplify a rear frame structure, to reduce the cost and to enhance the degree of freedom for arrangement of various kinds of mechanical apparatuses by composing the rear of a car body frame of a transmission case and the rear frame. SOLUTION: A rice transplanter is obtained as follows. The frame rear Fr is composed by connecting and fixing the rear frame 14 for supporting a quadruple link mechanism to the transmission case 3. The rear frame 14 is composed by installing a pair of left and right flexible frame members 15 formed by standing vertical frame parts 15B and 16B for pivoting the front ends of an upper link 17 and lower links 18 from the rear end of transverse frame parts 15A and 16A having front ends connected and fixed to the transmission case 3. In the rice transplanter, the tops of the flexible frame members 15 and 16 are mutually connected and integrated with a rear wheel fender supporting member 19. Link pivoting parts 24 and 24 are mutually and relatively positioned with a shaft member 21 pivoting the upper link 17. COPYRIGHT: (C)2004,JPO
