PROBLEM TO BE SOLVED: To provide a rice transplanter capable of being used without requiring lubrication oil supply over a long period and also easily performing suitable lubrication oil supplement. SOLUTION: This rice-transplanter is provided by installing an oil-feeding port 50 for supplying the lubrication oil and an oil amount-confirming hole 52 at a driving case 24 equipped with a seedling-transplanting mechanism-driving shaft 16 as freely driving. The oil amount-confirming hole 52 is constituted so as to confirm the oil surface level in the driving case and also arranged at a lower arranged height than that of the oil-feeding port 50.
