PROBLEM TO BE SOLVED: To provide a support for a fruit support that has a simple structure and is capable of adjusting the extension angle of an arm portion easily and certainly regardless of the structure of a cultivation bed.SOLUTION: A mounting member 2 has a mounting portion 5 and a bearing portion 6 and is fixed to a metal tube member 32 by the mounting portion 5. The bearing portion 6 has an axial insertion hole 7 and a perpendicular engaging face 8 around it. An arm member 3 has an axial portion 9 opposing to the bearing portion 6, and an axial cylinder part 12 engages the axial insertion hole 7 in relatively rotatable manner and in relatively movable manner to the axial direction. The engaging face 11 is possessed around the axial cylinder part 12. The arm member 3 supports a fruit support 34 on the upper surface. An engaging-and-releasing operation member 4 has a spring receiving member 14 and a spring 13. The extension angle of the arm member 3 with respect to the mounting member 2 can be adjusted in a state in which the mutual engagement of an engagement teeth 8a and 11a is released, by pushing the spring receiving member 14 from the mounting member 2 side against spring force.SELECTED DRAWING: Figure 1【課題】構造が簡易であり、腕部の延出角度の調整を栽培ベッドの構造に係わりなく容易、かつ確実に行える果実支持体用の支持具を提供する。【解決手段】取り付け部材２は、取り付け部５、軸受け部６を具備し、取り付け部５で金属管材３２に固定される。軸受け部６は、軸挿通孔７と、その周りの垂直の係合面８を具備する。腕部材３は、軸受け部６と対向する軸部９を具備し、軸筒部１２が軸挿通孔７に相対回転及び軸方向相対移動自在に嵌合する。軸筒部１２周りに係合面１１を有する。腕部材３は、上面に果実支持体３４を支持する。係脱操作部材４は、ばね受け部材１４と、ばね１３とを具備する。取り付け部材２側からばね受け部材１４をばね力に抗して押し込んで、係合歯８ａ，１１ａの相互係合を解いた状態で、取り付け部材２に対する腕部材３の延出角度を調整することができる。【選択図】図１
