PROBLEM TO BE SOLVED: To provide a joint which can reliably hold a wire member so as not to deform the wire member.SOLUTION: A block joint 1 which is mounted on a pillar for horticulture to support a wire member for plant holding and can deform elastically comprises: a first holding part 11 which holds an outer peripheral surface of the pillar by a pillar hole 10 penetrating in a vertical direction an aperture 12 which is opened over a full length of the pillar hole 10 in the vertical direction, and allows the first holding part 11 to attach/detach to/from the pillar an insertion hole which is opened toward the top face a side and extended downward, and into/from which a bent end part of the wire member bending downward is inserted/extracted and a first holding groove 31 which is formed on the top face a and extended from the insertion hole to an end part of the top face, and which holds a horizontal part continuing to the bent part of the wire member.COPYRIGHT: (C)2015,JPO&INPIT【課題】ワイヤ状部材を変形しないように確実に保持することができるジョイントを提供する。【解決手段】園芸用の支柱に取り付けられて植物保持用のワイヤ状部材を支持する、弾性変形可能なブロック状のジョイント1において、上下方向に貫通された支柱孔10により支柱の外周面を挟持する第1挟持部11と、支柱孔10をその上下方向の全長にわたって開口し、支柱に対する第1挟持部11の着脱を可能にする開口部12と、上面a側に開口するとともに下方に向かって延び、ワイヤ状部材の下方に屈曲された屈曲端部が上方から挿脱される挿入孔と、上面aに形成されて挿入孔から上面の端部まで延設されるとともに、ワイヤ状部材の屈曲端部に連続する水平部を保持する第1保持溝31とを備える。【選択図】図1
