PROBLEM TO BE SOLVED: To provide a support holding device for plant cultivation, which extremely easily fixes a holding bar to a support, and holds the holding bar in a surely stable state even when a large force is added by a strong wind or the like.SOLUTION: The support holding device is configured such that a second attachment 14 to be attached to a support 3 includes a cylindrical member 15 slidable in the vertical direction, a receiving projecting portion 17 receiving a central laterally installed bar 6 bridged between the supports 3, and a round bar-like first projecting portion 27 and second projecting portion 28 each projecting to the front and the horizontal direction from the outer peripheral surface of the cylindrical member 15. Furthermore, a first support bar portion 33 suppressing swinging in the horizontal direction of the support 3 has a first hooking portion 34 hookable to the first projecting portion 27 on the upper end, and a second hold bar 9 suppressing swinging in the cross direction of the support 3 has a second hooking portion 40 hookable to the second projecting portion 28 on the upper end.COPYRIGHT: (C)2011,JPO&INPIT【課題】支柱に対して保持棒材を極めて簡単に固定することができるとともに、強風等によって大きな力が加わっても、確実に安定した状態で保持することが可能な植物栽培用の支柱保持装置を提供する。【解決手段】支柱3に装着される第二アタッチメント14は、上下方向に摺動可能な筒状部材15と、支柱3間に架け渡される中央横設棒材6を受止める受止突部17と、筒状部材15の外周面から前方及び左右方向にそれぞれ突出する丸棒状の第一突出部27及び第二突出部28とを備える。また、支柱3の左右方向の振れを抑制する第一支持棒部33は、第一突出部27に掛止可能な第一掛止部34を上端側に有し、支柱3の前後方向の振れを抑制する第二保持棒材9は、第二突出部28に掛止可能な第二掛止部40を上端側に有する。【選択図】図2
