To provide a transplanter capable of avoiding inconvenience of bending right and left movable cantilevered placing stands by seedling load, causing a position gap between the stands and a corresponding transplantation mechanism and reducing transplantation precision in storing seedling stands at both right and left end sides and planter cases in a folded state.

In this transplanter constituted so as to store movable seedling placing stands 14 and 15 at both right and left end sides and movable planter cases 6 and 7 in a folded state, movable seedling placing stand stays 34 for slidably supporting the movable seedling placing stands 14 and 15 are extended at sides of the movable planter cases 6 and 7.
