PROBLEM TO BE SOLVED: To provide a seedbed holding unit which can securely and strongly hold a seedbed with a simple structure without damaging a plant.SOLUTION: A seedbed holding unit 160 holds a seedbed B used in plant cultivation, and includes a first holding member 170 and a second holding member 180 which can relatively rotate around a predetermined rotation axis A. A first claw part 173 is arranged in a fixed state on the first holding member 170. A second claw part 183 is arranged in a fixed state on the second holding member 180. When the first holding member 170 and the second holding member 180 are rotated relatively, the seedbed holding unit 160 holds the seedbed B by the first claw part 173 and the second claw part 183.COPYRIGHT: (C)2016,JPO&INPIT【課題】簡素な構造で、植物に損傷を与えることなく、苗床を確実かつ強固に把持することが可能な苗床把持ユニットを提供すること。【解決手段】植物栽培に用いられる苗床Bを把持する苗床把持ユニット160であって、所定の回転軸Aを中心として相対的に回転可能な第1把持部材170および第2把持部材180を備え、第1把持部材170には、第1爪部173が固定状態で設けられ、第2把持部材180には、第2爪部183が固定状態で設けられ、第1把持部材170および第2把持部材180を相対的に回転させることで、第1爪部173および第2爪部183によって苗床Bを挟む苗床把持ユニット160。【選択図】図5
