PROBLEM TO BE SOLVED: To solve the problems wherein a rotation case, a planting claw part and a connecting member are provided to increase in number of parts, resulting in increasing the weight to increase the cost.SOLUTION: In a rice transplanter 1, a plurality of planting transmission cases 46 are projected backward in parallel from a planting frame 49, a longitudinally midway part of a rotation case 44 is rotatably supported on both right and left side surfaces of the rear part of the planting transmission case 46, and a planting claw part 45 is rockably disposed in both end parts in the longitudinal direction of the rotation case 44. The planting claw part 45 includes: a claw body 71 for cutting off a seedling a push rod 72 for pushing out the seedling cut off in the vicinity of a field surface a planting claw shaft 64 projected from the rotation case 44 a cam 75 fixed to the planting claw shaft 64 a push arm 76 rocked in contact with the cam 75 a spring 73 energizing the push rod 72 in the projecting direction and a claw case 45a to which the above members are fitted, wherein the claw case 45a is constructed to be bilaterally symmetrical.COPYRIGHT: (C)2014,JPO&INPIT【課題】従来、回転ケースと植付爪部と連結部材を備えていたため部品点数が多くなり、重量増加を招き、コストアップにつながる、という問題等があった。【解決手段】植付フレーム49より複数の植付伝動ケース46を平行に後方へ突出し、該植付伝動ケース46の後部左右両側面に回転可能に回転ケース44の長手方向中途部を支持し、回転ケース44の長手方向両側端部に植付爪部45を揺動可能に配置する田植機1において、前記植付爪部45は、苗を切り取る爪体71と、圃場面近傍で切り取った苗を押し出すプッシュロッド72と、該回転ケース44から突出される植付爪軸64と、該植付爪軸64に固設されるカム75と、該カム75に当接して揺動されるプッシュアーム76と、前記プッシュロッド72を突出方向に付勢するバネ73と、これらを取り付ける爪ケース45aとを備え、該爪ケース45aは左右対称に構成する。【選択図】 図6
