According to the first aspect of the present invention, in the connected state of the divided seedling mounting bases (upper wall portions of the partition portions), one of the divided partition portions and the other upper wall portion are directly sandwiched by the fixing member. At the same time as the fixing, the supporting member for supporting the seedling holding member is sandwiched and fixed by the fixing member. As a result, the above-described fixing member is also used as a dedicated fixing structure for fixing the support member.

[VI] According to the feature of the second aspect, similar to the case of the first aspect, the "action" described in the above-mentioned [I] to [V] is provided, and in addition to this, the following " Action ". According to the feature of claim 2, in one and the other upper wall portions of the divided partitions in the same manner as in the case of claim 1 of the above [IV], the seedling placing surface of the seedling placing portion is orthogonal to the seedling placing surface. In addition to preventing displacement in the direction, displacement of the seedling in the longitudinal feed direction is prevented. In one and the other upper wall portions of the thus divided partitions, the displacement of the seedling placement portion in the direction orthogonal to the seedling placement surface and the displacement of the seedling in the vertical feed direction are prevented.

As a result, the connection of the seedling mountings is ensured, and the durability of the seedling mountings and the reliability of the support of the seedling mountings can be improved.

According to the first aspect of the present invention, in a support member for supporting a seedling holding member generally provided in a seedling mount for a seedling transplanter, the fixing member is also used as a fixing structure dedicated to fixing the supporting member. This eliminates the need for a dedicated fixing structure for fixing the support member, which is advantageous in terms of simplifying the structure.

According to the feature of the second aspect, the "effect of the invention" of the first aspect is provided similarly to the case of the first aspect, and in addition to the "effect of the invention", the following "invention" is provided. Of the effect. According to the feature of claim 2, in the upper wall portion of the divided partition portion, the positional deviation of the seedling mounting portion in the direction orthogonal to the seedling mounting surface and the positional deviation in the vertical feeding direction of the seedlings are increased. Since it can be reliably prevented by a fixing member separate from the wall, the connection state of the seedling mounting table is further ensured, and the durability of the seedling mounting table and the reliability of the support of the seedling mounting table are further improved. Could be improved.
