PROBLEM TO BE SOLVED: To provide a transplanting machine which has a high degree of freedom of design even when avoiding a mainframe and can maintain high body strength. SOLUTION: The traveling vehicle body 40 is provided with left and right traveling devices 44 for traveling in the field, a seedling supply device 43 for supplying seedlings, and planting devices 20a, 20b for receiving seedlings from the seedling supply device 43 and planting them in the field. The main frames 103 of the traveling vehicle body 40 are provided on both the left and right sides, and the left and right distances of the rear end portions of the left and right main frames 103 are wider than the left and right distances of the front end portion and are within the left and right width of the seedling feeding device. The traveling transmission cases 38 that are transmitted to the traveling device 44 are rotatably provided on both the left and right sides of the vehicle 40, the steering handles 47 are provided at the rear of the traveling vehicle body 40, and the front sides of the left and right main frames 103 are connected to the transmission case 38. Each of them is attached to the axle cover 101, and the rear side is connected to both left and right sides of the handle frame 104 supporting the steering handle 47. [Selection diagram]【課題】 メインフレームを避けても設計の自由度が高く、高い機体強度を保持可能な移植機を提供すること。【解決手段】 走行車体４０に圃場を走行する左右の走行装置４４と、苗を供給する苗供給装置４３と、苗供給装置４３から苗を受けて圃場に植え付ける植付装置２０ａ，２０ｂを備え、走行車体４０のメインフレーム１０３を左右両側に設け、左右のメインフレーム１０３の後端部の左右間隔は、前端部の左右間隔よりも広く、且つ苗供給装置の左右幅内に収めると共に、走行車体４０の左右両側に、走行装置４４に伝動する走行伝動ケース３８を各々回動可能に設け、走行車体４０の後部に操縦ハンドル４７を設け、左右のメインフレーム１０３の前側は伝動ケース３８に連結される車軸カバー１０１に各々装着され、後側は操縦ハンドル４７を支持するハンドルフレーム１０４の左右両側に各々連結される構成とする。【選択図】 図７
