PROBLEM TO BE SOLVED: To provide auxiliary tools that make it easy to cut each seedling-raising pot from a connected body of seedling-raising pots.SOLUTION: An auxiliary tool 3 comprises an outer frame portion 31 and an inner frame portion 32. The inner frame portion 32 marks off the inner space of the outer frame portion 31 into a plurality of spaces into which respective seedling-raising pots 100A are inserted. The inner frame portion 32 is provided with an arrangement portion 321 having an arrangement surface 321a on which a connecting portion 103 is arranged. On both sides of the arrangement portion 321, there is an insertion space in which the tip of a pushing member 43 that pushes down the upper part of the seedling-raising pot 100A can be pushed below the arrangement surface 321a.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2020,JPO&INPIT【課題】育苗ポット連結体から各育苗ポットを切断しやすくする補助具を提供する。【解決手段】補助具3は、外枠部31と、内枠部32とを備える。内枠部32は、外枠部31の内側空間を、各育苗ポット100Aが挿入される複数の空間に区画している。内枠部32には、連結部103が配置される配置面321aを有した配置部321が設けられている。配置部321の両側には、育苗ポット100Aの上部を押し下げる押込部材43の先端を、配置面321aよりも下方まで押し込むことが可能な挿入空間が存在する。【選択図】図1
