a seedling cultivation device of a transplanter is provided with an operational part cover cap (62) protruding from a box (11) internally provided with an end several-row cultivation clutch (50) to the outside of the box. The operation part cover cap covers an operational pin (61) and a spring (64) for applying forces on the operation pin (61). In the interior of the operation part cover cap (62), a linkage mechanism (65) for enabling the operational pin (61) to be linked with a clutch operational element (66) is connected on the operational pin (61). Switching operation is performed to the end several-row cultivation clutch by utilizing an insertion box wall, and the clutch operational part is linked with the operational pin through the linkage mechanism, easily avoiding malfunction brought about by dirt or muddy water attachment. |
