PROBLEM TO BE SOLVED: To provide a rice transplanter for preventing deformation of planting depth variable arm, etc., by thrusting up force from the underside of floats. SOLUTION: In this rice transplanter in which the base edges of planting depth variable arms 37 are rotatably pivoted on and connected to the base parts of floats 33 and 34 installed below a planting frame 31, the height position of a planting depth adjusting lever 38 connected to the tip of the planting depth variable lever 37 and extended is changed so that the floating heights of the fronts of the floats 33 and 34 are changed so as to adjust the planting depth, a stopper 42 for preventing the base parts of the floats 33 and 34 from rising by thrusting up force from the underside of the floats 33 and 34 is laid between the planting depth variable arm 37 and the planting frame 31.
