PROBLEM TO BE SOLVED: To eliminate shaking at the tip of a seedling taking out claw, and to accurately and surely perform seedling taking out operation, by always making toeing contact of the gear of a planetary gear mechanism as a fixed plane.;SOLUTION: The seedling taking out apparatus for a transplanter has a seedling claw bed 33, equipped with a seedling taking out claw 32 and a reciprocative motion means 36 that makes the seedling claw bed 33 reciprocate, while drawing a substantially elliptical locus D, enters the seedling taking out claw 32 into a pot part P at the downside of one end of the approximately elliptic locus D and then withdraws the seedling taking out claw from the pot part P at the upper side of one end so as to take out seedlings N. The reciprocative motion means 36 has a sun shaft 43, a sun gear 42 concentric with the sun shaft 43, a gear case 47 that is mounted on the sun shaft 43 and supports an idler gear 44 and a planetary gear 45, and a rotary arm 48 that connects a planetary shaft 46 to the claw spindle 61 of the seedling claw bed 33. The center-to-center dimension K1, from the planetary gear 45 to the sun gear 42, is made different from the center-to-center dimension K2, from the planetary gear 45 to the claw spindle 61. The seedling taking out apparatus is equipped with an urging means 76 for urging the claw spindle 61 via the seedling claw bed 33 upward.;COPYRIGHT: (C)2008,JPO&INPIT
